/* Shared Hostome calendar picker (mission HOSTOME_M46_CLAUDE_R4_RESERVATIONS_
   FILTER_MODEL_AND_SHARED_UI).

   Extracted VERBATIM from css/pages/index.css (Dashboard's own calendar,
   introduced across missions M45-R16/R17) so index.html and
   reservations.html consume the exact same rules - one file, never a fork.
   Dashboard's own markup/behavior is unchanged; only the CSS moved.

   Two consumers:
   - Dashboard (frontend/domains/dashboard/dashboard.page.js): single
     selected date, operational dots (.dash-cal-dot.is-arrival/-departure/
     -stay) + .dash-cal-legend.
   - Reservations (frontend/domains/reservations/reservation-period-picker.js):
     range selection, NEVER renders .dash-cal-legend, uses the additive
     .is-range-start/.is-range-end/.is-in-range cell modifiers below (new
     in this mission, harmless/unused by Dashboard). */

/* M46-R5 calendar hover fix: `button.dash-cal-cell:hover` (specificity

   (each 0,2,0) on the `background` property alone - `color` is untouched by
   the hover rule, so it stays whatever the winning background rule left it
   (white on these three), producing white text on the hover rule's light
   `--surface-2` background: invisible. Each state gets its own explicit
   :hover rule at specificity 0,3,0 (or 0,3,1 for the .is-in-range button
   selector below), which always wins over the plain 0,2,1 hover rule
