/* ===== HEIGHT =====
 * The `sectionHeight` attribute lowers that floor; render.php emits
 * lwp-csm-h-{value} (100vh is the default, so it needs no rule here). Two
 * things to keep if you edit this:
 *   - each rule repeats the vh/svh pair, svh last, exactly like the base rule
 *     above — a short section still wants the iOS-toolbar-friendly unit;
 *   - the selectors carry both classes. A single-class `.lwp-csm-h-60vh` would
 *     tie the base rule on specificity and win on source order alone, so a
 *     reshuffle in this file could quietly switch a section back to full
 *     height; the two-class form wins on specificity and cannot be reordered
 *     into silence.
 * `auto` removes the floor: the section becomes its content + the base padding.
 * These are minimums, never caps — content taller than the floor still wins.
