# S05: Key Moment Card Text Overflow Fix
**Fixed key moment card text overflow — long filenames truncate with ellipsis, titles wrap gracefully, no horizontal bleed from sidebar cards.**
## What Happened
Applied four targeted CSS property changes to the `.technique-moment*` rules in `frontend/src/App.css`:
1. `overflow: hidden` on `.technique-moment` — clips any child content that escapes card bounds
2. `word-break: break-word` on `.technique-moment__title` — long titles wrap instead of overflowing (wrapping preferred over truncation since titles are meaningful content the user needs to read)
3. `max-width: 100%` on `.technique-moment__source` — the source filename now respects actual container width instead of the previous `max-width: 20rem` which could exceed the sidebar's inner width
4. `min-width: 0` on `.technique-moment__meta` — required for flex child truncation to work reliably; without this, flex items can refuse to shrink below their content size
Single task, single file. Frontend builds cleanly.
## Verification
Frontend build passes with zero errors (768ms). All four CSS properties confirmed present in the correct rules via grep and manual file inspection. overflow: hidden on .technique-moment (line 1517), word-break: break-word on .technique-moment__title (line 1526), max-width: 100% on .technique-moment__source (line 1548), min-width: 0 on .technique-moment__meta (line 1535).

# S05: Key Moment Card Text Overflow Fix — UAT
**Milestone:** M007
**Written:** 2026-03-30T19:42:38.680Z
## UAT: Key Moment Card Text Overflow Fix
### Preconditions
- Chrysopedia web UI running (http://ub01:8096)
- At least one technique page exists with key moments that have long source filenames (20+ characters)
### Test 1: Long filename truncation
1. Navigate to a technique page that has key moments with long source video filenames
2. Observe the key moment cards in the right sidebar
3. **Expected:** Source filename text stays within card bounds, truncated with ellipsis (`...`) if too long. No horizontal scrollbar appears on the sidebar or page.
### Test 2: Long title wrapping
1. Find or create a key moment with a title longer than the card width (~20rem)
2. View the technique page containing that moment
3. **Expected:** The title text wraps to multiple lines within the card. Full title is readable. No horizontal overflow.
### Test 3: Timestamp + filename meta row
1. View a key moment card that has both a timestamp range (e.g., "01:23:45 01:25:00") and a long filename
2. **Expected:** The meta row wraps if needed (flex-wrap). Timestamp and filename stay within card bounds. No text overlaps or clips illegibly.
### Test 4: Narrow viewport
1. Resize browser window to ~900px width (technique page sidebar becomes compressed)
2. View key moment cards
3. **Expected:** Cards adapt — text still truncates/wraps within bounds. No horizontal page scroll caused by card content.
### Edge Cases
- Key moment with no source filename (empty `.technique-moment__source`): card renders normally without blank space issues
- Key moment with very short title (1-2 words): no visual regression, card looks normal

# S06: Mobile Viewport Overflow Fix — Technique Pages and Global Content
**Goal:** Fix mobile viewport overflow across content pages. Ensure all containers respect viewport width with max-width: 100%, overflow-wrap: break-word, box-sizing: border-box. Focus on technique pages (tag rows, body text, metadata) but audit all pages for the same class of issue.
**Goal:** Technique pages and global content render cleanly on mobile viewports (~412px) — no horizontal overflow, tags wrap, metadata stays within bounds.
**Demo:** After this: Technique page on Galaxy S25 Ultra renders cleanly — body text wraps, tags don't overflow, metadata stays within viewport, no horizontal scroll
## Tasks
- [x] **T01: Added flex-wrap, max-width, and tighter mobile gaps to prevent horizontal overflow on ~412px viewports** — Add CSS rules to `frontend/src/App.css` that prevent horizontal overflow on narrow viewports (~412px Galaxy S25 Ultra). CSS-only task — no TSX changes.
**Context:** The technique page has several elements that overflow on mobile:
1. `.technique-header__tags``display: inline-flex` with no `flex-wrap: wrap`, so multiple topic tags blow out horizontally
2. `.technique-header__creator-genres` — rendered in TechniquePage.tsx (line 235) with class `technique-header__creator-genres` but has **zero CSS rules**. Genre pill elements inline without wrapping.
3. `.version-switcher__select` (line ~2521) — can be wide with long version text like "v3 — Mar 30, 2026, 02:15 PM"
4. `.app-main` (line 199) — has `padding: 0 1.5rem` which is generous for mobile; tighten to 1rem
5. `.technique-header__meta` (line ~1408) — `flex-wrap: wrap` already present but gap could be tighter on mobile
**What already works (do NOT touch):**
- `.technique-banner--version` already has `flex-wrap: wrap`
- `.technique-chain__flow` already wraps ✅
- `.technique-prose__json` already has `overflow-x: auto`
- `.technique-moment__source` fixed in S05 ✅
- `html, body` have `overflow-x: hidden`
- Estimate: 20m
- Files: frontend/src/App.css
- Verify: cd frontend && npm run build && echo '--- Build OK ---' && cd .. && grep -q 'flex-wrap: wrap' frontend/src/App.css && grep -q 'technique-header__creator-genres' frontend/src/App.css && echo '--- All checks passed ---'

# S06 Research: Mobile Viewport Overflow Fix — Technique Pages and Global Content
## Summary
Straightforward CSS fix — no new technology, no architectural changes. The technique page has several elements that overflow on narrow viewports (~412px CSS width for Galaxy S25 Ultra). The existing 768px breakpoint collapses the two-column grid but doesn't address tag wrapping, metadata spacing, or element sizing. A single CSS-only task in `App.css` targeting the `@media (max-width: 768px)` and/or `@media (max-width: 640px)` blocks.
## Recommendation
Single task: add mobile-specific CSS rules for technique page elements that overflow. All work in `frontend/src/App.css`. No TSX changes needed.
## Implementation Landscape
### File: `frontend/src/App.css` (3150 lines)
**Existing breakpoints:**
- `@media (max-width: 768px)` at line 1357 — only has technique grid collapse (1fr) and sidebar un-sticky
- `@media (max-width: 640px)` at line 812 — admin/queue responsive rules + header stack
- `@media (max-width: 640px)` at line 2106 — public page responsive rules (home hero, nav, creators, topics)
**Overflow sources identified on technique page (target: 412px viewport):**
1. **`.technique-header__tags` (line 1414)** — `display: inline-flex; gap: 0.25rem` with **no `flex-wrap: wrap`**. Multiple topic tags will blow out horizontally on any narrow viewport. Fix: add `flex-wrap: wrap`.
2. **`.technique-header__creator-genres`** — rendered in TSX but has **no CSS rule at all**. It's a bare `<span>` containing pill elements. If a creator has multiple genre tags, they'll just inline without wrapping. Fix: add a rule with `display: inline-flex; flex-wrap: wrap; gap: 0.25rem`.
3. **`.technique-header__meta` (line 1408)** — has `flex-wrap: wrap` ✅, but children (category badge + tags span + quality badge) have no `max-width` constraint. The inline-flex tags span inside this doesn't wrap (see #1). Fixing #1 cascades here.
4. **`.version-switcher__select` (line 2521)** — could be wide with long "v3 — Mar 30, 2026, 02:15 PM" text. Fix: add `max-width: 100%` or truncation in the 640px breakpoint.
5. **`.technique-chain__flow` (line 1586)** — monospace font, `display: flex; flex-wrap: wrap` ✅. Already wraps correctly. No fix needed.
6. **`.technique-prose__json` (line 1484)** — `overflow-x: auto` ✅. Scrolls on overflow. No fix needed.
7. **`.technique-moment__source` (line 1544)** — already fixed in S05: `max-width: 100%; overflow: hidden; text-overflow: ellipsis` ✅.
8. **`.technique-page` (line 1338)** — `max-width: 64rem` with no padding. Relies on `.app-main` padding (0 1.5rem). On mobile the 1.5rem side padding is fine but could be reduced to 1rem for more breathing room.
9. **`.technique-banner--version` (line ~2548)** — `display: flex` with inline button. On narrow viewport the button may push content off-screen. Fix: add `flex-wrap: wrap` in mobile breakpoint.
**Global elements (already handled):**
- `html, body` have `overflow-x: hidden` (line 149) — catches any stray overflow
- `.app-header` stacks vertically at 640px ✅
- `.app-nav` gaps reduce at 640px ✅
- `.app-main` padding: `0 1.5rem` — sufficient for mobile
### What doesn't need changing:
- Grid collapse at 768px already works
- Key moment cards (fixed in S05)
- Signal chain flow (already wraps)
- JSON pre blocks (already scroll)
- Search results page (already has flex-wrap)
- Home page (already has 640px rules)
- Creators/Topics pages (already have 640px rules)
### Verification approach
1. `npm run build` — zero TypeScript/build errors
2. Grep for all new CSS properties to confirm they're in the right selectors
3. Optionally: run dev server → browser emulate Galaxy S25 Ultra (412×915) → navigate to a technique page → verify no horizontal scroll
### Natural task decomposition
This is a **single task** — all changes are CSS property additions/modifications in one file (`App.css`). The changes are:
1. Add `flex-wrap: wrap` to `.technique-header__tags`
2. Add `.technique-header__creator-genres` rule with `display: inline-flex; flex-wrap: wrap; gap: 0.25rem`
3. In `@media (max-width: 640px)` public section (~line 2106), add:
- `.technique-header__title` already shrinks font ✅
- `.version-switcher__select { max-width: 10rem; overflow: hidden; text-overflow: ellipsis }`
- `.technique-banner--version { flex-wrap: wrap; gap: 0.5rem }`
- `.app-main { padding: 0 1rem }` (tighter mobile padding)
- `.technique-header__meta { gap: 0.375rem }` (tighter gap)
4. Optionally reduce `technique-header__title` font further at 400px if 1.375rem still feels large
No TSX changes. No new files. No new dependencies.

1. `.technique-header__tags``display: inline-flex` with no `flex-wrap: wrap`, so multiple topic tags blow out horizontally
2. `.technique-header__creator-genres` — rendered in TechniquePage.tsx (line 235) with class `technique-header__creator-genres` but has **zero CSS rules**. Genre pill elements inline without wrapping.

5. `.technique-header__meta` (line ~1408) — `flex-wrap: wrap` already present but gap could be tighter on mobile
**What already works (do NOT touch):**

- `.technique-chain__flow` already wraps ✅
- `.technique-prose__json` already has `overflow-x: auto`
- `.technique-moment__source` fixed in S05 ✅
- `html, body` have `overflow-x: hidden`
## Inputs
- ``frontend/src/App.css` — existing stylesheet with technique page rules, 640px and 768px breakpoints`
## Expected Output
- ``frontend/src/App.css` — updated with mobile viewport overflow fixes: flex-wrap on tags, creator-genres rule, version-switcher max-width, tighter mobile padding and gaps`
## Verification
cd frontend && npm run build && echo '--- Build OK ---' && cd .. && grep -q 'flex-wrap: wrap' frontend/src/App.css && grep -q 'technique-header__creator-genres' frontend/src/App.css && echo '--- All checks passed ---'

**Added flex-wrap, max-width, and tighter mobile gaps to prevent horizontal overflow on ~412px viewports**
## What Happened
Applied five CSS changes to frontend/src/App.css: flex-wrap on .technique-header__tags, new .technique-header__creator-genres rule (existed in TSX with zero CSS), max-width + text-overflow on .version-switcher__select, tighter .app-main padding at 640px, and reduced .technique-header__meta gap at 640px. All changes prevent horizontal overflow on Galaxy S25 Ultra width viewports.
## Verification
npm run build passes (48 modules, 774ms). grep confirms flex-wrap: wrap and technique-header__creator-genres present in App.css.
