Root cause: inline onclick with JSON.stringify(title) broke when title
contained quotes, special chars, or was empty. The HTML attribute parser
got confused by mismatched quotes, so click handler never fired.
Fix:
- Replaced inline onclick handlers with data-action attributes
- Added single delegated click listener at document level
- Title stored in element dataset (no HTML quoting issues)
- Added escapeHtml() helper for safe rendering of titles/errors
Now clicking Preview in the right sidebar opens the fullscreen modal
correctly, regardless of filename characters.
Previously: clicking Preview in jobs list showed a small inline video
within the job card row.
Now: clicking Preview opens a centered fullscreen modal with:
- Large video player (up to 95vw × 85vh) — same experience as bottom
live-preview but accessible from jobs list
- Auto-play, controls, native HTML5 video player
- Title shown below video for context
- Download button + Close button
- Click outside or ESC key to close
- Backdrop blur for focus
Removes the obsolete inline <video> element that was rendered hidden
in each job card. Body scroll locked while modal open.
1. Preview endpoint now supports HTTP Range requests (HTTP 206 Partial)
- HTML5 video player needs Range support to seek/buffer properly
- Without it, video would cut off after a few seconds
- Returns chunks of 64KB on demand
2. Left panel (upload form) is now sticky (position: sticky)
- Stays in view while right panel (jobs list) scrolls
- On mobile (<800px) reverts to normal flow
- Refactored analyze_with_claude into shared _build_analysis_prompt + _parse_llm_response helpers
- New analyze_with_gemini() using Gemini 3.1 Pro ($2/M in, MMMLU 92.6% — best multilingual)
- Unified analyze_with_llm(provider) dispatcher with auto-fallback (Claude → Gemini)
- API endpoint accepts llm_provider in StartJobIn (claude/gemini/auto)
- Frontend dropdown to pick LLM
- Default model is now Sonnet 4.6 (was Haiku 4.5) — 3x quality at 3x price (~3 cents/video)
- Gemini support is opt-in: needs GEMINI_API_KEY env var to activate
- 3-sample voting for auto-detect (start/middle/end of song) prevents lang switching mid-song
- Lock detected language for full transcription
- Anti-hallucination: condition_on_previous_text=False, temperature=0.0
- compression_ratio_threshold=2.4 (rejects repetitive hallucinations)
- log_prob_threshold=-1.0 (rejects low-confidence segments)
- no_speech_threshold=0.6 (more aggressive silence detection)
- Default Whisper model changed: small → medium (better for all langs incl. Slavic)
