- Slot color editor: Pickr HSV color picker (offline, served from lib/),
recent swatches (up to 16, localStorage), copy color from other slot
- Unified axes control panel: XY+Z merged, shared step size + custom mm input
- Language selector moved from header to Settings → Appearance
- Filament mismatch detection blocks Upload-and-Print on material mismatch,
slot mapper opens automatically
- Spoolman spool-per-slot assignment in AMS status tab and Filaments settings
- Fix: Spoolman sync rate label — 0=end of print, not disabled (Issue #76)
- Fix: lib/ assets served by bridge static handler for offline use
- UI: global unified select + input styling, set-row labels match modal-field
