You are the closer — verify the assembled work actually delivers the slice goal, then compress everything into a slice summary. After you finish, a **reassess-roadmap agent** reads your slice summary to decide if the remaining roadmap still makes sense. The slice summary is also the primary record of what this slice achieved — future slice researchers and planners read it as a dependency summary when their work builds on yours.\n\nWrite the summary for those downstream readers. What did this slice actually deliver? What patterns did it establish? What should the next slice know?\n\nAll relevant context has been preloaded below — the slice plan, all task summaries, and the milestone roadmap are inlined.

Single column on mobile. |\n| S03 | Key Moment Card Redesign | low | S02 | ⬜ | Key moment cards show title prominently on its own line, with source file, timestamp, and type badge on a clean secondary row |\n\n---\n\n### Slice Plan\nSource: `.gsd/milestones/M005/slices/S03/S03-PLAN.md`\n\n# S03: Key Moment Card Redesign\n\n**Goal:** Key moment cards show title prominently on its own line, with source file, timestamp, and type badge on a clean secondary metadata row.\n**Demo:** After this: Key moment cards show title prominently on its own line, with source file, timestamp, and type badge on a clean secondary row\n\n## Tasks\n- [x] **T01: Split key moment card header into standalone h3 title and flex-row metadata div, replacing single-row __header layout** — Restructure the key moment card in TechniquePage.tsx and App.css so the title is a standalone prominent element and the metadata (source filename, timestamp, content type badge) sits on a clean secondary row below it.\n\n## Context\n\nThe technique page sidebar (22rem, established by S02 via D019) contains key moment cards. Currently the card header is a single flex row with `flex-wrap: wrap` containing title, source, timestamp, and badge as siblings. At 22rem width this wraps unpredictably. The fix splits the header into two explicit rows.\n\n## Steps\n\n1. Read `frontend/src/pages/TechniquePage.tsx` around lines 413–430 to locate the key moment card JSX (the `.technique-moment` list items inside the Key Moments section within `.technique-columns__sidebar`).\n\n2. Restructure the card JSX:\n   - Pull the title `<span className=\"technique-moment__title\">` out of the `__header` div and place it before it as a standalone element. Change from `<span>` to `<h3>` for semantic correctness (it's a sub-heading within the Key Moments `<h2>` section).\n   - Rename the remaining `<div className=\"technique-moment__header\">` to `<div className=\"technique-moment__meta\">` — it now contains only source, timestamp, and badge.\n   - The `<p className=\"technique-moment__summary\">` stays unchanged after the meta div.\n   - Target structure per card:\n     ```\n     <li className=\"technique-moment\">\n       <h3 className=\"technique-moment__title\">{km.title}</h3>\n       <div className=\"technique-moment__meta\">\n         {km.video_filename && <span className=\"technique-moment__source\">...}  \n         <span className=\"technique-moment__time\">...</span>\n         <span className=\"badge badge--content-type\">...</span>\n       </div>\n       <p className=\"technique-moment__summary\">{km.summary}</p>\n     </li>\n     ```\n\n3. Read `frontend/src/App.css` around lines 1337–1380 to locate the key moment card styles.\n\n4. Update CSS:\n   - `.technique-moment__title`: Change to `display: block; margin: 0 0 0.25rem 0; font-size: 0.9375rem; font-weight: 600; line-height: 1.3;` — block display gives it its own line, bottom margin separates from meta row. Reset h3 default margins.\n   - Add `.technique-moment__meta` with the same styles as the current `__header`: `display: flex; align-items: center; gap: 0.5rem; margin-bottom: 0.25rem; flex-wrap: wrap;`\n   - Remove or comment out `.technique-moment__header` (no longer used in JSX). If other code references it, keep it but it should be dead CSS after the JSX change.\n   - All other moment card styles (`.technique-moment__time`, `.technique-moment__source`, `.technique-moment__summary`, `.badge--content-type`) remain unchanged.\n\n5. Verify:\n   - Run `cd frontend && npx tsc --noEmit` — zero errors\n   - Run `cd frontend && npm run build` — succeeds\n   - Grep for any remaining references to `technique-moment__header` in .tsx files to confirm it's fully replaced\n   - Confirm no hardcoded hex/rgba values in new or modified CSS rules\n\n## Constraints\n\n- Sidebar width is fixed at 22rem (D019). Card must look good within this constraint.\n- Do NOT modify `.badge` or `.badge--content-type` classes — they're shared across the app.\n- Preserve the `<ol>` list wrapper and `<li>` card container structure.\n- Use only existing CSS custom properties for any color values.\n- The `<h3>` for the title should not introduce unwanted default browser margins — reset with explicit margin in CSS.\n  - Estimate: 20m\n  - Files: frontend/src/pages/TechniquePage.tsx, frontend/src/App.css\n  - Verify: cd frontend && npx tsc --noEmit && npm run build && ! grep -q 'technique-moment__header' src/pages/TechniquePage.tsx && echo 'PASS'\n\n---\n\n### Requirements\nSource: `.gsd/REQUIREMENTS.md`\n\n# Requirements\n\n## R001 — Whisper Transcription Pipeline\n**Status:** validated\n**Description:** Desktop Python script that accepts video files (MP4/MKV), extracts audio via ffmpeg, runs Whisper large-v3 on RTX 4090, and outputs timestamped transcript JSON with segment-level timestamps and word-level timing.

This causes `relationship(...)` calls below it to fail with \"MappedColumn object is not callable\".\n\n**Fix:** Import with an alias: `from sqlalchemy.orm import relationship as sa_relationship` and use `sa_relationship(...)` throughout. Alternatively, rename the database column, but the spec defines `relationship` as the column name so we preserved it.\n\n## Docker Compose variable interpolation and `:?` syntax\n\n**Context:** `${VAR:?error message}` in docker-compose.yml makes `docker compose config` fail when the variable is unset, even if `env_file: required: false` is used. The `required: false` only controls whether the `.env` file must exist — it does NOT provide defaults for variables referenced with `:?`.\n\n**Fix:** Use `${VAR:-default}` for variables that need a fallback, or ensure the variable is always set in the environment.\n\n## Host port 8000 conflict with kerf-engine\n\n**Context:** The kerf-engine Docker container (`kerf-engine-kerf-engine-1`) binds to `0.0.0.0:8000`. When testing the Chrysopedia API locally (outside Docker), curl requests to `localhost:8000` hit the kerf-engine container instead of the local uvicorn process, even when uvicorn binds to `127.0.0.1:8000`.\n\n**Fix:** Use an alternate port (e.g., 8001) for local testing. In Docker Compose, chrysopedia-api maps `127.0.0.1:8000:8000` which is fine because it goes through Docker's port forwarding, but will conflict with kerf-engine if both stacks run simultaneously. Consider changing one project's external port mapping.\n\n## asyncpg rejects timezone-aware datetimes for TIMESTAMP WITHOUT TIME ZONE columns\n\n**Context:** SQLAlchemy models using `default=datetime.now(timezone.utc)` produce timezone-aware Python datetimes. When the PostgreSQL column type is `TIMESTAMP WITHOUT TIME ZONE` (the default), asyncpg raises `DataError: can't subtract offset-naive and offset-aware datetimes`. This only surfaces when running against a real PostgreSQL database — SQLite-based tests won't catch it.\n\n**Fix:** Use `datetime.now(timezone.utc).replace(tzinfo=None)` in the `_now()` helper, or change the column type to `TIMESTAMP WITH TIME ZONE`. We chose the former since the existing schema uses naive timestamps.\n\n## asyncpg NullPool required for pytest-asyncio integration tests\n\n**Context:** When using a session-scoped SQLAlchemy async engine with asyncpg in pytest-asyncio tests, the connection pool reuses connections across fixtures and test functions. This causes `InterfaceError: cannot perform operation: another operation is in progress` because the ASGI test client's session holds a connection while cleanup/verification fixtures try to use the same pool.\n\n**Fix:** Use `poolclass=NullPool` when creating the test engine. Each connection is created fresh and immediately closed, eliminating contention. Performance cost is negligible for test suites.\n\n## Testing Celery tasks that use sync SQLAlchemy: patch module-level globals\n\n**Context:** Pipeline stages in `pipeline/stages.py` create their own sync SQLAlchemy engine/session via module-level `_engine` and `_SessionLocal` globals (because Celery is sync, not async). Tests need to redirect these to the test database, but the engine is created lazily at module scope.\n\n**Fix:** Patch the module globals directly: `unittest.mock.patch.object(stages, '_engine', test_engine)` and `unittest.mock.patch.object(stages, '_SessionLocal', test_session_factory)`. This redirects all DB access in stage functions to the test database without modifying production code.\n\n## Lazy imports in FastAPI handlers defeat simple mock patching\n\n**Context:** When a FastAPI handler imports a function lazily (inside the function body) like `from pipeline.stages import run_pipeline`, patching `routers.ingest.run_pipeline` has no effect because the name is re-bound on every call from the source module.\n\n**Fix:** Patch at the source module: `unittest.mock.patch('pipeline.stages.run_pipeline')`. The lazy import will pick up the mock from the source module. This applies to any handler that uses lazy imports to avoid circular dependencies at module load time.\n\n## Separate async/sync clients for FastAPI vs Celery\n\n**Context:** The Chrysopedia backend has both sync Celery tasks (pipeline stages using `openai.OpenAI`, `QdrantClient`, sync SQLAlchemy) and async FastAPI handlers. Reusing sync clients in async handlers blocks the event loop; reusing async clients in Celery risks nested event loop errors.\n\n**Fix:** Create separate client classes: `SearchService` (async, for FastAPI request path) wraps `openai.AsyncOpenAI` and `AsyncQdrantClient`. The pipeline's `EmbeddingClient` and `QdrantManager` (sync, for Celery) remain untouched. This doubles the client code surface but eliminates the async/sync mismatch class of bugs entirely.\n\n## Mocking SearchService at the router dependency level for tests\n\n**Context:** The search endpoint creates a `SearchService` instance internally. Testing search results with real embedding API and Qdrant is fragile (external dependencies). Mocking individual `openai.AsyncOpenAI` or `AsyncQdrantClient` is complex.\n\n**Fix:** Mock `SearchService` at the router level by patching the service instance in the endpoint function. This gives full control over search results in tests without complex async mock setup. Used in `test_search.py` — mock returns canned `SearchResponse` dicts.\n\n## Frontend detail page without a single-resource GET endpoint\n\n**Context:** The review queue backend has `GET /review/queue` (list, paginated) but no `GET /review/moments/{id}` for fetching a single moment. The MomentDetail page needs to display one specific moment by ID from the URL params.\n\n**Fix:** MomentDetail fetches the full queue with `limit=500` and filters client-side by ID. This works for a single-admin tool with small datasets but would not scale. If the moment count grows significantly, add a dedicated `GET /review/moments/{id}` endpoint to the review router.\n\n**Update (M004/S01):** Fixed properly — added `GET /review/moments/{id}` endpoint. Always add single-resource GET endpoints alongside list endpoints.\n\n## CSS custom property count estimation\n\n**Context:** When planning a full color abstraction pass (replacing all hardcoded hex/rgba with CSS custom properties), initial estimates based on counting unique colors will significantly undercount the required tokens.\n\n**Rule:** Plan for 2-3x the obvious color count. Reasons: hover/focus/active state variants, badge/status color pairs (background + text), subtle vs strong accent variants, shadow colors, overlay backgrounds, and distinct semantic contexts (surface vs input vs card). M004/S02 planned ~30, needed 77.\n\n## Chained selectinload for cross-relation field population\n\n**Context:** When an API response needs a field from a joined relation (e.g., `key_moment.source_video.filename`), Pydantic's `from_attributes` auto-mapping can't traverse the join. The field appears as a flat attribute on the response schema but comes from a different table.\n\n**Fix:** Chain `.selectinload()` in the query (e.g., `.selectinload(TechniquePage.key_moments).selectinload(KeyMoment.source_video)`), then post-process in a loop to copy the joined value into the schema field. This keeps the query efficient (two SELECTs) and the response schema flat.\n\n## Pre-overwrite snapshot pattern for article versioning\n\n**Context:** Need to track content versions without complex CDC (change data capture) infrastructure. The content lives in a single mutable row that gets overwritten on each pipeline run.\n\n**Pattern:** Before mutating the row, SELECT its current state, serialize relevant fields to JSONB (`content_snapshot`), attach pipeline metadata (prompt file hashes, model config) as a second JSONB column, and INSERT into a versions table. Use best-effort error handling — snapshot failure logs ERROR but doesn't block the primary write. Composite unique index on (entity_id, version_number) enforces ordering at DB level.\n\n## Stage 4 classification data stored in Redis (not DB columns)\n\n**Context:** The KeyMoment SQLAlchemy model doesn't have `topic_tags` or `topic_category` columns. Stage 4 classification needs somewhere to store per-moment tag assignments that stage 5 can read.\n\n**Fix:** Store classification results in Redis under key `chrysopedia:classification:{video_id}` with a 24-hour TTL. Stage 5 reads from Redis. This avoids schema migrations during initial pipeline development. The data is ephemeral — if Redis loses it, re-running stage 4 regenerates it.\n\n## QdrantManager uses random UUIDs for point IDs\n\n**Context:** `QdrantManager.upsert_technique_pages()` and `upsert_key_moments()` generate `uuid4()` for each Qdrant point. Re-indexing the same content creates duplicate points rather than updating existing ones.\n\n**Fix (deferred):** Use deterministic UUIDs based on content hash (e.g., `uuid5(NAMESPACE, f\"{technique_slug}:{section}\")`) so re-indexing overwrites the same points. This should be addressed before running the pipeline on production data to avoid index bloat.\n\n## Non-blocking side-effect pattern for external service calls in pipelines\n\n**Context:** Celery pipeline stages that call external services (embedding API, Qdrant) should not fail the entire pipeline if those services are down. Stage 6 (embed_and_index) is valuable but not critical — the pipeline's primary output (technique pages in PostgreSQL) doesn't depend on it.\n\n**Fix:** Use `max_retries=0` and a catch-all exception handler that logs WARNING and returns without raising. The pipeline orchestrator chains stage 6 after stage 5 but a failure there doesn't prevent `processing_status` from reaching its final state. This pattern applies to any \"best-effort enrichment\" stage in a pipeline.\n\n## Container healthcheck tool availability varies by base image\n\n**Context:** Qdrant (distroless-ish), Ollama, and nginx-alpine images don't have curl or wget. Standard healthcheck patterns like `curl -f http://localhost:PORT/health` fail silently inside these containers.\n\n**Fix by image:**\n- **Ollama:** Use `ollama list` (built-in CLI)\n- **Qdrant:** Use `bash -c 'echo > /dev/tcp/localhost/6333'` (bash is available)\n- **nginx-alpine:** Use `curl` (available) but NOT busybox `wget` (fails on localhost)\n- **Celery worker (same image as API):** Use `celery -A worker inspect ping` instead of HTTP healthcheck\n\n**Rule:** Always `docker exec <container> <healthcheck-cmd>` to verify the command works before deploying.\n\n## XPLTD domain setup flow\n\n**Context:** Adding a new external domain (like chrysopedia.com) to the XPLTD infrastructure requires three steps across two machines.\n\n**Flow:**\n1. **AdGuard on ub01 (10.0.0.10):** Add DNS rewrite via API: `POST /control/rewrite/add` with `{domain, answer: \"10.0.0.9\"}`\n2. **nginx on nuc01 (10.0.0.9):** Create server block in `/etc/nginx/sites-enabled/{domain}.conf` with `proxy_pass http://10.0.0.10:{port}`\n3. **Certbot on nuc01:** `sudo certbot --nginx -d {domain}` (requires external DNS A record or CNAME pointing to public IP first)\n\n**Note:** The AD DNS servers (10.0.0.15/.16) may already have CNAME entries for domains. Check `nslookup {domain} 10.0.0.15` before assuming setup is needed. ub01's resolv.conf uses AD DNS, not AdGuard, so `curl {domain}` from ub01 requires the AD DNS chain to resolve.\n\n## Alembic env.py sys.path needs both local and Docker paths\n\n**Context:** Alembic's env.py imports from `database` and `models`, which live in `backend/` locally but at `/app/` (the WORKDIR) inside Docker. The original `sys.path.insert(0, \"../backend\")` works locally but fails in Docker.\n\n**Fix:** Add both paths: `sys.path.insert(0, os.path.join(os.path.dirname(__file__), \"..\", \"backend\"))` AND `sys.path.insert(0, os.path.join(os.path.dirname(__file__), \"..\"))`. The second resolves to `/app/` inside Docker.\n\n## Nginx stale DNS after Docker container rebuild\n\n**Context:** When an API container behind an nginx reverse proxy in Docker Compose is rebuilt (new container ID, new internal IP), the nginx container's DNS resolver cache still points to the old IP. Requests through nginx return 502 Bad Gateway even though the API is healthy on its new IP.\n\n**Fix:** Restart the nginx/web container after rebuilding upstream containers: `docker compose restart chrysopedia-web-8096`. Alternatively, configure nginx with `resolver 127.0.0.11 valid=10s;` in the upstream block to use Docker's embedded DNS with a short TTL, but the restart is simpler for a single-admin deployment.\n\n---\n\n### Task Summary: T01\nSource: `.gsd/milestones/M005/slices/S03/tasks/T01-SUMMARY.md`\n\n---\nid: T01\nparent: S03\nmilestone: M005\nprovides: []\nrequires: []\naffects: []\nkey_files: [\"frontend/src/pages/TechniquePage.tsx\", \"frontend/src/App.css\"]\nkey_decisions: [\"Changed title element from span to h3 for semantic correctness within Key Moments h2 section\", \"Renamed __header to __meta since it now contains only metadata\"]\npatterns_established: []\ndrill_down_paths: []\nobservability_surfaces: []\nduration: \"\"\nverification_result: \"TypeScript compilation (tsc --noEmit) passes with zero errors.

A complex slice with 5 tasks across multiple subsystems needs thorough verification and a detailed summary. Scale the work below accordingly.\n\nThen:\n1. Use the **Slice Summary** and **UAT** output templates from the inlined context above\n2. If a `GSD Skill Preferences` block is present in system context, use it and the `<available_skills>` catalog in your system prompt to decide which skills to load and follow for this unit, without relaxing required verification or artifact rules.\n3. Run all slice-level verification checks defined in the slice plan. All must pass before marking the slice done. If any fail, fix them first.\n4. If the slice plan includes observability/diagnostic surfaces, confirm they work. Skip this for simple slices that don't have observability sections.\n5. If the slice involved runtime behavior, fill the **Operational Readiness** section (Q8) in the slice summary: health signal, failure signal, recovery procedure, and monitoring gaps. Omit entirely for simple slices with no runtime concerns.\n6. If this slice produced evidence that a requirement changed status (Active → Validated, Active → Deferred, etc.), call `gsd_save_decision` with scope=\"requirement\", decision=\"{requirement-id}\", choice=\"{new-status}\", rationale=\"{evidence}\". Do NOT write `.gsd/REQUIREMENTS.md` directly — the engine renders it from the database.\n7. Write `/home/aux/projects/content-to-kb-automator/.gsd/milestones/M005/slices/S03/S03-SUMMARY.md` (compress all task summaries).\n8. Write `/home/aux/projects/content-to-kb-automator/.gsd/milestones/M005/slices/S03/S03-UAT.md` — a concrete UAT script with real test cases derived from the slice plan and task summaries. Include preconditions, numbered steps with expected outcomes, and edge cases. This must NOT be a placeholder or generic template — tailor every test case to what this slice actually built.\n9. Review task summaries for `key_decisions`. Append any significant decisions to `.gsd/DECISIONS.md` if missing.\n10. Review task summaries for patterns, gotchas, or non-obvious lessons learned. If any would save future agents from repeating investigation or hitting the same issues, append them to `.gsd/KNOWLEDGE.md`. Only add entries that are genuinely useful — don't pad with obvious observations.\n11. Call `gsd_complete_slice` with milestone_id, slice_id, the slice summary, and the UAT result. Do NOT manually mark the roadmap checkbox — the tool writes to the DB and renders the ROADMAP.md projection automatically.\n12. Do not run git commands — the system commits your changes and handles any merge after this unit succeeds.\n13. Update `.gsd/PROJECT.md` if it exists — refresh current state if needed.\n\n**You MUST call `gsd_complete_slice` with the slice summary and UAT content before finishing. The tool persists to both DB and disk and renders `/home/aux/projects/content-to-kb-automator/.gsd/milestones/M005/slices/S03/S03-SUMMARY.md` and `/home/aux/projects/content-to-kb-automator/.gsd/milestones/M005/slices/S03/S03-UAT.md` automatically.**\n\nWhen done, say: \"Slice S03 complete.\"","display":false,"id":"63ed3c3a","parentId":"513e2be1","timestamp":"2026-03-30T08:55:49.898Z"}

Below the metadata row, verify the summary text\n2. **Expected:** Summary paragraph appears below the metadata row, not interleaved with title or metadata\n3. **Expected:** Summary text is visually distinct from the title (lighter weight, standard font size)\n\n### TC4: Cards without source filename\n1. Find a key moment card where `video_filename` is null/empty (or verify behavior if all moments have filenames)\n2. **Expected:** The metadata row shows only timestamp and content type badge — no empty space or broken layout where the filename would be\n\n### TC5: Semantic HTML structure\n1. Open browser DevTools on a technique page\n2. Inspect a key moment card's DOM structure\n3. **Expected:** Title is an `<h3>` element with class `technique-moment__title`\n4. **Expected:** Metadata wrapper is a `<div>` with class `technique-moment__meta`\n5. **Expected:** No elements with class `technique-moment__header` exist anywhere on the page\n\n### TC6: Mobile single-column layout\n1. Resize browser to ≤768px width (or use device emulation)\n2. Navigate to a technique page\n3. **Expected:** Key moment cards still render correctly in single-column layout\n4. **Expected:** Title still on its own line, metadata row still below it, no layout breakage\n\n### TC7: No visual regression on shared badge styles\n1. Check that `.badge--content-type` badges on key moment cards look identical to badges used elsewhere in the app (e.g., on topic pages or search results)\n2. **Expected:** Badge color, padding, border-radius, and font-size are unchanged","verification":"All four verification checks from the slice plan pass:\n1. `npx tsc --noEmit` — zero TypeScript errors (exit 0)\n2. `npm run build` — Vite production build succeeds, 46 modules transformed (exit 0)\n3. `grep technique-moment__header` in TSX — no matches, confirming full replacement (exit 0)\n4. No hardcoded hex/rgba values in new or modified CSS rules (exit 0)\n\nAdditionally confirmed: JSX structure matches the target layout exactly (h3 → meta div → summary paragraph), and dead `__header` CSS class fully removed from App.css."}}],"api":"anthropic-messages","provider":"anthropic","model":"claude-opus-4-6","usage":{"input":1,"output":1948,"cacheRead":67989,"cacheWrite":958,"totalTokens":70896,"cost":{"input":0.000005,"output":0.0487,"cacheRead":0.0339945,"cacheWrite":0.005987500000000001,"total":0.088687}},"stopReason":"toolUse","timestamp":1774860984952}}

The system is deployed and running on ub01 at `http://ub01:8096`.\n\n### What's Built\n\n- **Transcription pipeline** — Desktop script: video → ffmpeg audio extraction → Whisper large-v3 → timestamped transcript JSON\n- **6-stage LLM extraction pipeline** — Transcript segmentation → key moment extraction → classification/tagging → technique page synthesis → embedding/indexing. Per-stage model routing (chat vs thinking models). Resumable per-video per-stage.\n- **Article versioning** — Pre-overwrite snapshots with pipeline metadata (prompt SHA-256 hashes, model config) for benchmarking extraction quality across prompt iterations.\n- **Review queue UI** — Admin interface for approving/editing/rejecting extracted key moments.\n- **Search-first web UI** — Dark theme with cyan accents. Semantic search (Qdrant), topic/creator browse pages, technique detail pages with signal chain blocks and video source metadata.\n- **Docker Compose deployment** — API, worker, web, PostgreSQL, Redis, Qdrant, Ollama on ub01 with bind mounts at `/vmPool/r/services/chrysopedia_*`.\n- **Prompt template system** — Editable per-stage prompt files with SHA-256 tracking for reproducibility.\n\n### Stack\n\n- **Backend:** FastAPI + Celery + SQLAlchemy (async) + PostgreSQL + Redis + Qdrant\n- **Frontend:** React + TypeScript + Vite\n- **LLM:** OpenAI-compatible API (DGX Sparks Qwen primary, local Ollama fallback)\n- **Deployment:** Docker Compose on ub01, nginx reverse proxy on nuc01\n\n- **Pipeline admin dashboard** — Admin page at `/admin/pipeline` with video list, status badges, retrigger/revoke controls, expandable event log with token usage, collapsible JSON response viewer, and live worker status indicator. Pipeline events instrumented via `PipelineEvent` model (stage, event_type, token counts, JSONB payload).\n- **Technique page 2-column layout** — Prose content (summary + study guide) on left, sidebar (key moments, signal chains, plugins, related techniques) on right at desktop widths.
