Cast: card/list views, sort & filter, online voice picker, "Hear a line" sample button, AI character notes, import auto-save. Platform: WCAG 2.1 AA accessibility pass; German UI translation + language picker; installable PWA with offline shell; GZip + content-visibility virtualization + lazy images + Rehearser PCM memory cap (mobile stability); Playwright suite (desktop + iPhone); opt-in minified bundle build. Fixes: screenplay parser false characters; Fish-Speech inline-tag tones; narrator/voice pickers list full library; clone GUI rework; fish.audio import dedup; voice-ID rename; bulk-delete modal.
