Two issues behind "it just shows downloaded 100% / loads forever / crashes
after a couple seconds":
1. Progress was invisible during transcription. The 'transcribing' stage
only fired AFTER the first (slow) chunk, so the UI sat at "Loading
model… 100%" through the entire first inference and looked frozen.
- pipeline now emits a transcribing kickoff (progress 0) BEFORE the
first chunk and carries chunkIndex/chunkCount on every event.
- transcribeStore threads those through; the Library job card shows a
spinner, "Transcribing… N%", and "part i of N" so a long file's
progress is legible and obviously advancing.
2. Web crash on mobile. We picked WebGPU + fp16 whenever navigator.gpu
existed, but mobile WebGPU drivers crash on sustained fp16 Whisper
inference (transcribes a chunk, then the GPU process dies). Mobile web
now uses cross-origin-isolated multi-threaded WASM (slower but stable);
desktop keeps WebGPU.
Native's "loads forever" was the same missing-feedback problem — it was
grinding through chunks with no UI signal; the chunk counter now shows it.
tsc clean, 279 tests pass (pipeline progress test updated for the kickoff
event), web export OK.

The Library crammed five text nav-links into a non-wrapping row with no
bottom navigation — unusable on phones. Restructure the primary screens
into a bottom tab bar:
- Add src/app/(tabs)/_layout.tsx: <Tabs> with 5 tabs (Library, Search,
Study, Ask, Settings) with emoji icons and the accent active tint.
- Move index/search/study/ask/settings into the (tabs) route group; the
parens keep URLs unchanged (/, /search, /study, /ask, /settings).
- Root _layout becomes a Stack hosting (tabs) (headerless) plus the
secondary pushed screens (record, transcript/[id], courses, quiz,
bibliography), each with a back-button header.
- Drop the per-screen <Stack.Screen> headers from the moved tabs (titles
now come from Tabs); relocate Study's "Export Anki" action into the body.
- Library: remove the cramped header link-row and duplicate title; add a
"nothing uploaded" subheader and a Courses link.
Verified at 375px: tab bar pinned to the bottom, 5 even tabs, navigation
between tabs works. tsc clean, web export OK, 279 tests pass.
CI: build-apk now runs automatically on every push to master (after
deploy-web), so the APK at /wisp.apk tracks master instead of being
frozen at a stale tag.
