Adds the day timeline, team list, employee record and leave calendar.
The design export shipped data for these but no markup, so their layout
is designed here from the data shapes and the established style; only
Aperçu and the week grid are ports.
The day view carries a per-hour headcount band. Where the week view
answers "who works how much", this one answers "who is on the floor at
14:00", and the band makes coverage gaps visible without reading every
lane.
Two fixes the tests and linter caught:
- The poste derivation variables were missing from globals.css. Hues
and tiers were ported but not the --post-*-bg/fg/edge that consume
them, so every shift chip would have rendered colourless. The palette
test now asserts all 36 exist.
- ThemeToggle synced state in an effect. The document's data-theme
attribute is the real store — it is set by the inline script before
React exists — so it now subscribes with useSyncExternalStore instead
of keeping a copy that is wrong on first render.
Counter tests cover the DST cases in both directions: a 22:00–06:00
shift lasts 7 or 9 hours on the changeover nights, never 8.
