Wrap each DayChip in a container-query context so the chip layout
responds to the actual space available rather than the viewport width.
Breakpoints (per-chip width):
- < 72px (mobile, 7 chips in ~320px): compact — label + date + progress bar + badges only
- ≥ 72px (tablet+): show worked duration text below the date number; slightly larger padding/font
- ≥ 100px (desktop, 7 chips in ~750px wide main): larger date number, bigger worked label
The .chip-slot div in week/+page.svelte is the flex child (flex: 1,
min-width: 2.8rem) that feeds width into the container; .chip-wrap
inside DayChip carries container-type: inline-size and fills the slot.
- New DayChip.svelte component: weekday label, date number, progress
bar (worked/expected), kind badge (H/V/S), closed checkmark, today
highlight, selected state, accessible role=tab/aria-selected
- Week page: replace days-grid with horizontal scroll-snap chip strip
- Per-day workedMs: uses closed_days.worked_ms when closed, else sums
open entries for that day (so in-progress work shows immediately)
- dailyExpectedMs: evenly split hours_per_week across workdays; 0 for
weekends (no progress bar rendered for non-workdays)
- Progress bar turns amber when worked > expected (overtime)
- weekEntries stored in state (was discarded after computing set);
daysWithEntries now derived from weekEntries
