/* ---- Stack ----------------------------------------------------------------- */
/* The stack's height, for heroes that sit under it: an estimate per state
   (header 72px at every width — the Donate button sets it; announcement bar
   36px, 69px on ≤480px where its text takes two lines — WP-10l, it was 64)
   so the first paint is right; header.js then writes the measured value on
   <body> where it differs. Without the estimate the hero moved by ~60px on a
   phone once the script ran (CLS 0.03); with a wrong one the whole page was
   styled again (Lighthouse at 412px). Between 481 and 767px the bar may wrap
   to a second or third line: measured then. */
