/* ── layout safety net ──────────────────────────────────────────
   The page styling comes from the Tailwind Play CDN, which generates
   utility classes at runtime and can be slow, rate-limited or blocked
   on the live host — when that happens the flex/grid stacks collapse
   (e.g. the brand and the "Most read" list flow inline). These rules
   mirror Tailwind's own structural utilities from the reliably-loaded
   stylesheet, so the layout holds regardless. They are harmless no-ops
   whenever the CDN has applied them. */
