/* shared/landing-mobile.css
 * 2026-05-10 — mobile + slider hardening for /public/index.html.
 * Loaded AFTER index.html's inline <style> block so these rules win in source order
 * (no need for !important spam). Overrides the .lp-slider-btn rule on lines 215-219
 * and tightens spacing across the landing page on phone widths.
 *
 * Bugs this file addresses:
 *   1. Slider prev/next arrows invisible/under-tappable on mobile. The original
 *      rule positioned them with left:1rem / right:1rem and shrank them to 38x38px
 *      under 560px — too small for WCAG 2.5.5 (44x44 min) and easy to miss against
 *      a busy slide image. Now: 48x48 minimum, gold ring, 0.78 opacity ink panel,
 *      backdrop-blur, ALWAYS visible at every viewport.
 *   2. lp-foot 1fr-1fr on tablet/phone produced two cramped columns; stack
 *      single-column under 480.
 *   3. Various edge cases: lp-cta-row buttons clipping, lp-feat side-anchor on
 *      narrow widths, lp-slide caption overflow on 320px screens.
