facett-calendar — crate card

Reverse-engineered (from source — verify, don't trust the name)

• One-line pitch: A pure-egui Monday-first month-grid calendar facet with a date picker and marked events.
• Does: Draws a Swedish/ISO (Monday-first) month grid with month navigation and day selection; marks days with Events whose EventKind (e.g. deadline/SLA due, absence/leave) drives color, showing a count and the strongest color per day. Absence marking feeds the handover model. Calendar follows the facett Facet contract (title/ui/state_json); ui() returns the selected NaiveDate.
• Key deps: egui, chrono, serde/serde_json. Optional facett feature.
• Shape: lib, ~362 LOC single lib.rs (EventKind, Event, Calendar).
• Observed role in the workspace: Standalone widget, no in-repo consumer yet. Built in ordning; destined for facett. Pure egui + chrono.

• Why it exists (vs the obvious alternative):
• Hard constraint (airgap / no-C-deps / no-FFI / pure-Rust / etc.):
• Release cadence & independence (rides a parent? own repo someday?):
• Status (production / prototype / experimental / stubbed):
• Must-NOT-change invariant:
• Biggest known gap or TODO:
