/* =========================================================
   Film leader: cream paper, warm black, one signal yellow.
   Every colour is OKLCH. Neutrals sit on hue 70 (dark) to 88 (paper);
   the accent is one yellow family (hue 80 to 95), lightness does the work.
   Yellow is a fill (markers, playheads, highlights, primary buttons with ink text).
   Accent-coloured TEXT on light surfaces is --signal-ink; on dark it is --signal.

   The method on one page: a fixed-ratio map (circle stays a circle), phase brackets,
   the loop's centre names the Direct phase; phones get a compact rail with the loop drawn back.

   latest note) above a light time chart, all in one card. The chart is drawn at its real
   pixel width so every label keeps its set size; phones get a compact log instead of the chart.

   Each step is one poster that reads on its own as a screenshot:
   a chapter numeral, the headline, one visual, one "Done when" line.
   At 1440x900 a poster fits under the sticky deck bar; on phones it
   stays near one and a half screens. "What I did" sits under the poster,
   then any hands-on extras, then Your turn.
   Fresh class prefixes (pv-, s1- to s8-) so the older poster rules do not apply.
