Privacy Mode feature:
- Toggle in Admin > Settings enables automatic purge of download
history, session logs, and files after configurable retention period
- Default retention: 24 hours when privacy mode is on
- Configurable 1-8760 hours via number input
- When enabled, starts purge scheduler (every 30 min) if not running
- When disabled, data persists indefinitely
Admin panel consolidation:
- Removed separate 'Purge' tab — manual purge moved to Settings
- Settings tab order: Privacy Mode > Manual Purge > Welcome Message >
Output Formats > Change Password
- Toggle switch UI with accent color and smooth animation
- Retention input with left accent border and unit label
Backend:
- PurgeConfig: added privacy_mode (bool) and privacy_retention_hours
- Purge service: uses privacy_retention_hours when privacy mode active
- PUT /admin/settings: accepts privacy_mode + privacy_retention_hours
- GET /config/public: exposes privacy settings to frontend
- Runtime overrides passed to purge service via config._runtime_overrides
Queue toolbar:
- Filter tabs (All/Active/Completed/Failed) and action buttons (Download
All/Clear) share one row — filters left, actions right
- Download All moved from DownloadTable to DownloadQueue toolbar
- Clear button: muted style → red border on hover → 'Sure?' red confirm
state → executes on second click, auto-resets after 3s
- Clear removes all completed and failed jobs (leaves active untouched)
Admin format defaults:
- Settings tab has Video/Audio default format dropdowns
- Stored in settings_overrides (same as welcome_message)
- Public config returns default_video_format and default_audio_format
- UrlInput resolves Auto format against admin defaults — if admin sets
audio default to MP3, 'Auto' chip shows 'Auto (.mp3)' and downloads
convert accordingly
Cyberpunk animated background:
- Diagonal crossing lines (blue 45° + orange -45°) drift slowly (60s cycle)
- Subtle radial gradient pulse (8s breathing effect)
- Layered on top of the existing grid pattern
- All CSS-only, no JS — zero performance cost
- Only active on cyberpunk theme (scoped to [data-theme=cyberpunk])
