/* ============================================================
   SOI 2026 — Responsive hardening (mobile / tablet)
   Loaded AFTER styles.css. The Figma source had NO mobile frames,
   so this layer fixes the fixed-px components that overflow small
   screens (nav, hero, pills). Desktop (>768px) is left untouched.
   Uses design tokens only — no new colors, no magic numbers.
   ============================================================ */

/* ---------- Global box-sizing reset (applies at ALL widths) ----------
   The design assumes border-box (c-cta-pill / c-tag-pill / c-stat-tile set it
   explicitly) but the bundle has no global reset, so full-bleed elements with
   width:100% + horizontal padding (.c-hero, .c-site-footer, .c-site-header)
   rendered ~96px wider than the viewport → horizontal scroll. Border-box fixes
   it everywhere, desktop included. */
