/* Site map design layer.
 *
 * The presentation layer for Components/Pages/SitemapPage.razor. Global CSS,
 * linked from App.razor, so the same two rules the sibling page sheets call out
 * apply here:
 *
 * 1. Nothing confines these rules to this page, so every selector is qsm-
 *    prefixed or a descendant of one. No bare element selectors.
 * 2. Any @keyframes would carry the qsm- prefix too, so they cannot collide
 *    with the compiled Tailwind bundle or with home's qh-, pricing's qp-, the
 *    blog's qb- or the help centre's qc- animations.
 *
 * These rules are unlayered and Tailwind v4's utilities live inside @layer, so
 * they win regardless of specificity. Keep every selector class-based.
 *
 * Palette is the logo ramp the pricing, blog and help-centre pages share:
 * #a22dea (magenta-violet) → #7b5ee5 → #5b5de2 (indigo-blue), with #4f46e5 as
 * the primary. Deliberately one accent rather than a per-card hue ramp — the
 * page is a dense index and a card is told apart by its heading, not its
 * colour.
 *
 * Reading order the layout is built around: a compact hero → a search card that
 * filters the list below it → a masonry of count-badged cards, each a menu with
 * its pages, three-level menus carrying collapsible sub-groups.
 *
 * The masonry is CSS multi-column, not grid. A grid would give every card in a
 * row the height of the tallest one, which on a page whose cards run from one
 * link to seventeen leaves most of them mostly empty; columns pack by height
 * instead. break-inside on the card is what stops one splitting across the
 * column boundary.
