Task #301.
Fonts:
- Extracted 22 curated font files from the user's uploaded zip into
artifacts/tx-os/public/fonts/ (DIN Next LT Arabic ×5, Tajawal ×7,
Helvetica Neue LT Arabic ×3, Helvetica Neue ×5, Majalla ×2).
- New artifacts/tx-os/src/custom-fonts.css with @font-face blocks
using font-display: swap; imported from index.css.
- Replaced FONT_OPTIONS in editable-cell.tsx with the curated set;
each <option> previews in its own font family.
Attendee keyboard nav:
- EditableCell: new onTabNext / onTabPrev props, captured into refs
so the empty-deps useEditor always sees the latest callback.
handleKeyDown now intercepts Tab and Shift+Tab (preventDefaults +
saveEdit + dispatches the matching callback).
- AttendeeFlow:
- new chainStartAdd path that bypasses the hasAnyPending UI gate
so Tab can chain a fresh pending row even while one is open
(state-level guard in setPendingAttendee still prevents overlap).
- new focusedAttendeeIdx state lets a sibling row request edit
mode on a target row via startInEditMode + onStartedEditing.
- findPrevPersonInSection walks back through items[] and stops at
a subheading, so Shift+Tab never crosses a section boundary;
no-op on the first row of a section (saveEdit still runs).
- Existing person row passes onTabNext (chain new pending after i)
and onTabPrev (focus prev person in same section).
- Pending row passes the same pair using
inlineGhostTargetListIdx ?? items.length as the start anchor.
Non-attendee EditableCells (meeting title, merge title, subheadings)
are unchanged — they pass no tab callbacks so default browser
focus traversal still applies.
Verified: TS clean, e2e covers forward Tab chain, Shift+Tab between
existing rows, first-in-section no-op, and Shift+Tab from the
pending row.
