/* ══ THE MEASURES PAGE (drills hub) ════════════════════════════════════════
   Was a 210px auto-fill card grid, four colour-coded domains, and a bloom-lit
   hero — the other surface still reading as a template. The drills hub and the
   back page ask the reader the same question ("which one do you want to try?"),
   so this borrows the back page's answer: a section head, entries NUMBERED the
   way a paper numbers its puzzles, and dotted leader rules between them.

   The four domains stay, but as DEPARTMENTS — a ruled head and a mono slug,
   not four accent hues. The old --dacc mapped speed→teal and memory→purple;
   both resolve into ink under the two-ink discipline, so the colour was doing
   no work while still reading as a colour-coded dashboard.
