/*
 * mobile-fixes.css — overlay stylesheet loaded AFTER style.css on every
 * xraygraphdb.emtailabs.com page. Targets the patterns that broke on
 * small viewports: fixed-min tables, wide pre/code blocks, hero grids
 * that didn't stack tightly enough, undersized touch targets, and
 * the 1539-line demos / 9680-line docs pages that have hand-written
 * inline layouts not covered by style.css's breakpoints.
 *
 * Strategy: pure overlay, no edits to style.css. Anything we ship here
 * either tightens the existing breakpoints or wraps offending elements
 * defensively. Easy to roll back by removing the <link rel="stylesheet"
 * href="mobile-fixes.css"> tag from each page.
 *
 * Audit: 2026-05-16 — user reported "not mobile ready at all" against
 * the full marketing site.
