Tapping an event in the week/day timeline opens a full-screen detail
destination (MD3 list→detail, not a bottom sheet) overlaying the calendar
with a slide transition. One card per field (when, calendar, location,
description, attendees, recurrence) with leading icons; location taps open
a maps intent. Loading/Failure/Success throughout.
Recurrence is humanized from the RRULE — e.g. "Every week on Tue and Thu
until 31 Dec 2026" — covering FREQ/INTERVAL/BYDAY/UNTIL/COUNT with
abbreviated, italicised day names and localized list formatting, falling
back to a generic label for rules it can't render.
Also:
- fix: recurring events failed to open (series row stores DURATION, not
DTEND, so the mapper dropped them as EventNotFound). The detail keeps
them and shows the tapped occurrence's own times from Instances.
- feat: month day cell → opens the day view anchored to that date.
- build: add material-icons-extended (R8 strips unused icons in release).

Day view as a one-column slice of the week view: shared TimedBlock/
AllDaySpan layout, per-day swipe navigation, hoisted noon-centred scroll,
animated all-day strip, and a compact top bar showing the full date.
- DayUiState / DayViewModel / DayScreen under ui/day
- reuse layoutDay/layoutAllDay/coversDay from the week package
- add Day to IMPLEMENTED_VIEWS; CalendarHost routes it explicitly
- day_today_action strings (en/de)

- Rounded, permanently-soft day-column scroll viewport via two viewports
sharing one scroll state (gutter + columns stay aligned); plain
rectangular column cards inside
- Vertical scroll position now persists across week swipes; noon-centring
only runs on first entry into the week view (from month/day)
- All-day strip height is hoisted + animated, shared by both swipe pages,
so it slides along and resizes smoothly instead of jumping
- Multi-line event time label so the end time isn't clipped in narrow
columns; hour labels centred in the gutter
- Calendar-week (ISO) badge in the header gutter, aligned with the date
numbers; dropped the redundant "All-day" gutter label
- Small breathing room between the top section and the timeline

Replace the throwaway debug screen with the first real calendar UI and a
functional Month <-> Week switcher, on Material 3 Expressive.
Month view (S1):
- Material 3 Expressive card-per-day grid; only the current month's weeks
render (neighbouring days left blank)
- per-day event dots with "+N" overflow, today via primaryContainer
- spring-based press feedback from the active motion scheme
- swipe + drawer navigation, Loading/Failure/Success states
Week view (S2):
- vertical time schedule with overlap-resolved lanes (per-day clipping,
midnight spanning, instant events)
- all-day / multi-day events as connected horizontal spans
- single scroll container (gutter + day columns stay aligned), columns
bundled in a rounded container, noon-centred on load
- top section colour-shifts with the app bar on scroll; swipe navigation,
three states
Shared / infra:
- CalendarHost holds the active view; RootScreen renders it post-permission
- ui/common building blocks: CalendarDrawer, CalendarFailure,
ViewSwitcherPill, pastelize, observable locale, M3 Expressive slide
transition (motionScheme fastSpatialSpec)
- unit tests for the week layout (lanes, clipping, all-day spans)
- build: compileSdk 37, material3 pinned to 1.5.0-alpha21 for Expressive

READ_CALENDAR permission declared. Strings split into English master
(values/) and German (values-de/) with the Loading/Failure/Success
generic state strings used across screens. Backup rules let DataStore
back up by default with no file-based content. Theme stub delegates
real theming to Compose; the Activity-level XML theme only sets
transparent system bars and dark-mode hint.
