/*
 * Month calendar. design/DESIGN-SYSTEM.md §4.17, grid §3.4 (repeat(7,1fr), 6px).
 *
 * Week starts Monday. Five cell states: available, selected, fully booked, past
 * (which the theme also uses for "beyond the booking horizon" -- the same
 * "not offered" meaning, and the design has no sixth state for it) and the
 * leading blank.
 *
 * §4.17 RECOMMENDs the hover the prototype lacks; it is applied to selectable
 * cells only.
 *
 * TODO token: rgba(255,255,255,0.22), the sub-label colour of a full day, has no
 * token (tokens.css has 0.27 as --sp-text-disabled and 0.40 as --sp-text-40).
