/* ── Short viewports (13–14" laptops) ─────────────────────────
   Two pages overflow the bottom edge on a 13" MacBook Air (~770–870px of
   usable viewport, less with a bookmarks bar). Both are keyed on HEIGHT, not
   width, so large-but-tall displays keep the intended design untouched.

   /writing/ — the hero's 280px vertical padding pushed the first row of cards
   to ~722px, so the page looked postless until you scrolled. Below these caps
   the hero's own min-height: 50vh takes over and it scales with the viewport.

   Homepage — the stack (topbar 105.6 + art 461.5 + copy 118.8 + the Pac-Man
   planets strip 143.6) totals ~830px, so the Pac-Man was clipped by the
   bottom edge. Height is reclaimed from the art and the surrounding
   whitespace, never from the Pac-Man itself — it is the element that has to
   stay whole. */
