- screenshot example inits i18n and captures both zh-CN and en-US
(docs/screenshot-window{,-en}.png)
- dock tabs size to content (no more 64px truncation); viewer/panel
titles follow the design (素材查看器·name etc.)
- mock project carries V1/V2 video + A1/A2 audio clips rendered as
rounded green bars; timeline clip geometry/rounded corners match the
design; status bar visible with full content; audio meter strip
docked at the program viewer's right edge; project explorer rows
have icons
- tests/waveform_e2e.rs: waveform cache extracts real peaks and hits
cache on re-query (P4 acceptance)
