The stay-bands restructure changed the calendar markup to per-week rows (.cal-weekdays / .cal-week / .cal-week-days / .cal-week-bands) but styles.css still only styled the old flat .calendar-grid, so day cells stacked vertically. Adds the 7-column grid layout for the new structure plus the missing stay-band styles (lanes, rounded ends, hover), and updates the narrow-screen rules.
Entries gain an optional inclusive end_date (backfilled via migration): flights and travel longer than 24h show a continuation marker on following days, and a new stay entry type marks a time frame in one area (e.g. 3 days Venice) rendered as continuous bands across the calendar weeks. Stays feed the map route as stops; the route summary gains stays count and a chronological areas list with day spans. 49 API tests.
Docker creates ./data root-owned on the host, but the app runs as the unprivileged node user, causing SQLITE_CANTOPEN on first deploy. New entrypoint starts as root, chowns DATA_DIR, then drops privileges with setpriv. Compose keeps the SQLite database in ./data next to the compose file. Also trims scripts/ and playwright artifacts from the image.
