   Large screens (2026-10-25, docs/js-series/layout-audit.md, "Prototype"). From 1280 px the page frame grows with the
   screen (1216 px at 1280, 1536 at 1920, 1880 at 2560; at most 105rem, so it follows the type) and the hero, the header
   and the body share its left edge; the paragraphs keep their 68ch. From 1280 the rule card splits in two, the five steps
   sit three and two (the two centred), and until 1600 the capsule list keeps 65rem (its "+" stays near its question).
   From 1600 the five steps sit on one row and the journey takes the left of the page, with the playgrounds, the films
   and the links beside it. Presentation mode keeps its 1280 px slide (every rule stops at :root.is-presenting).
