/**
 * Variant CSS: booking--calendar-week-grid
 *
 * Faux weekly calendar: centered head (kicker + headline + deck) over five day
 * columns (Mon-Fri). Each day holds a day label + a vertical stack of time
 * slots. Free slots are accent-tinted, clickable chips (real wp:button); taken
 * slots are dimmed, struck placeholders (wp:html). A legend + a "full schedule"
 * CTA close the section. No backend — slots are visual only. Text stays --ink
 * (polarity-aware); free slots + CTA take --accent. The 5-up grid wraps to
 * 3 / 2 columns on narrower screens. Part of the `booking` role.
