/* =========================================================
    CALENDAR PAGE  —  Boundary Prime
    Self-contained trio stylesheet. core.css (global reset)
    is loaded first by base.html.

    The whole page is themed through CSS variables: the dark
    palette lives in :root, and body.light-mode swaps the same
    tokens for a warm light palette. Default is dark (matches
    the Events sibling); the toggle follows the booking page.
