/* pakmud — mobile first, big clear type for older eyes. Text size: html[data-size] 1–6 (14/16/18/20/24/28 px), the
   pages start at 4 so the buttons go both ways.
   Colours from the ปักหมุด brand (brand/brand.mjs): แดงพริก #f2553d, ครีมข้าวเหนียว #fff3e2, โกโก้ #3b2620. The brand red is
   3.4:1 against white, so it carries the mascot, lines and fills, while text and button fills use --accent, a deeper
   chili (≥ 4.7:1 on the cream, 5.2:1 under white text); --soft is ≥ 7.9:1 for small text. */
