Windows for all three year types, the fallbacks (anniversary without a hire
date, a day the month cannot have), usage counted across the calendar-year
boundary, carry-over chained over periods rather than years, deleteYear over a
shifted period, and the reads with and without a viewer.
For comp: excluded from usage, a half comp day still costing nothing,
converting a vacation day back, and comp_used reported on its own.
* feat(vacay): read-only calendar shares on the server (#444, #667)
* feat(vacay): shared calendars card and ring overlay on desktop
* feat(vacay): share sheet and calendar rings on mobile
* test(vacay): cover the calendar share flows
* docs(vacay): document read-only calendar sharing
* feat(vacay): support half vacation days (#552)
Log a vacation day as a half day (0.5) as well as a full day and count it
as such against the entitlement. A "Half day" mode joins the calendar
toolbar on desktop and mobile; half days render as a diagonal half-fill in
the day cell, and the used/remaining totals carry the fraction.
Closes#552
* refactor(vacay): half-day as a per-person toggle with a corner badge
The diagonal half-fill collided with the two-person split — one person's
half day looked like two people off. Drop the diagonal: the cell fill keeps
showing who is off, a half day gets a small corner ½ badge, and a hover
tooltip lists who is off on that date and how much (only when a half day is
present). Logging moves from a third mode to a Half-day toggle that applies
to the selected person, on desktop and mobile.
* feat(vacay): mark half days with an orange corner dot
Swap the ½ badge for a small orange dot in the bottom-right corner, mirroring
the blue trip dot — quieter in the grid, and the hover tooltip still spells
out who is on a half day.
* fix(vacay): make the fraction migration idempotent
The crosswalk test replays the migration tail (rewind + re-run), which expects
every later migration to be idempotent. Guard the vacay_entries ADD COLUMN
behind a pragma_table_info check so the second run is a no-op. Also only set
dayVisual's `half` flag when true, so full days keep their exact
{ background, numColor } shape for the mobile day-model unit test.
* style(vacay): nudge the mobile day dots slightly inward
The blue trip dot and orange half-day dot sat right in the cell corner on
mobile; move both a touch toward the centre so they read cleaner.
