Checkpoint: Voice & AI Fix: (1) Maya now uses Studio-O (female) and Chris uses Studio-Q (male) — both previously had wrong gender voices. All 5 characters now have distinct voices: Alex=Journey-D, Sam=Journey-O, Jordan=Journey-F, Maya=Studio-O, Chris=Studio-Q. (2) AI Tool Finder system prompt upgraded to senior consultant persona with specific action guidance and 2-3 sentence reasons per recommendation. Token limit raised to 1200, timeout to 30s. Dark mode text colour fixed in AI summary. "Listen to episode" shortcut button added to each recommendation card. 5 new vitest tests for voice gender correctness. 101 tests passing.

Checkpoint: Root cause: selectCast required complexity score ≥6 to include all 5 characters, but most cards score 2-4. Maya and Chris were almost never selected. Fix: Jordan/Maya/Chris now rotate as guest slots. Simple cards (score ≤1) get Alex+Sam+1 rotating guest. Medium cards (score 2-3) get Alex+Sam+2 rotating guests. Complex cards (score ≥4) get all 5. Updated 22 vitest tests. 96 tests pass.

Checkpoint: Root cause of silent jingle/outro: AudioContext auto-suspends after long async operations (episode generation takes 10-30s). When source.start(0) was called on a suspended context, it fired silently and onended fired immediately. Fixed by awaiting _audioCtx.resume() inside playAudioBuffer() before creating the BufferSource. This ensures the context is always in 'running' state before playback begins.

Checkpoint: Root cause of missing intro jingle found via browser test: loadAudioBuffer returned null when called while a fetch was already in flight (no promise caching). Fixed by storing in-flight Promises in _audioBufferPromises so concurrent callers await the same fetch. unlockAudioContext() now immediately stores both promises so playJingle always gets a real AudioBuffer, not null.

Checkpoint: Two bugs fixed: (1) outro was firing when stop() was called because audio.src='' triggers onended — fixed with isStoppedRef guard that is set before clearing src and checked at the top of playNext. (2) Jingle buffers now pre-load immediately when AudioContext is unlocked so there's no race condition. All 95 tests pass.

Checkpoint: Root cause: user gesture chain breaks after async/await on iOS Safari, so new Audio().play() silently fails. Fix: AudioContext (Web Audio API) is unlocked synchronously in playCard/playDeck on the user tap, stays unlocked permanently. Jingle and outro now use AudioContext.createBufferSource() which never needs a gesture, even after long async fetches.

Checkpoint: Root cause: reused HTMLAudioElement had stale onended handler that fired immediately without playing. Fix: playAudioFile() creates a fresh element each time and returns a Promise. Jingle now plays on every episode start (not just non-cached). Outro plays after last segment via clean Promise chain.

Checkpoint: Root cause of missing jingle/outro: browser fetch() to CDN was blocked by CORS. Fix: both MP3 files are now in client/public and served as same-origin static assets at /stratalign-intro.mp3 and /stratalign-outro.mp3. AudioContext uses these paths directly — no CORS, no proxy needed.

Checkpoint: Fix intro jingle and outro stinger not playing on iOS (pre-fetched Blob + fresh audio element per play). Added 10 PM-specific joke templates to the script generation prompt so every episode has at least 2 relatable PM jokes woven naturally into the conversation.

Checkpoint: Fix mindmap node text clipping (accurate char-width, 3 lines for root nodes, light-mode colour) and fix compare card search modal scroll on iOS Safari (height+overflow-hidden+min-h-0)

Checkpoint: StratAlign Theater v6 — new upbeat intro jingle (BPM=128, synth bass, snare, hi-hats, bright bell) + outro stinger (descending mirror motif) that plays after the final episode segment

Checkpoint: StratAlign Theater v5 — jingle fixed (dedicated audio element, pre-loaded), podcast script rewritten for NPR-meets-The-Office energy with cold opens, personality clashes, and rapid-fire takeaways

Checkpoint: StratAlign Theater v4 — intro jingle (3.5s broadcast-style arpeggio + chime) plays before fresh episodes, skipped on cache replays
