/* Punch page — the ONE hand-written stylesheet for the ONE template.
   Source of truth: the Claude Design handoff `design_handoff_punch_page/README.md`
   (project 91bad551-0afe-4b33-b2cc-542800445376). Every hex, size, weight,
   letter-spacing, radius and spacing step below is transcribed from it; the prototype
   carries them inline only because of its format constraint (see PUNCH-DESIGN §3.0).

   Descriptive prose (footnotes, notice bodies, the privacy rows, the status line, the date and
   sub-lines) was scaled up 10% on 2026-08-19 by request, rounded to the nearest 0.5px. Headings,
   uppercase labels, buttons and data figures were deliberately NOT touched — scaling those too
   would just enlarge the page and lose the hierarchy the increase was meant to improve.

   Light is the default and the primary set; dark is `prefers-color-scheme: dark` only.
   Every colour is declared HERE in :root and merely re-pointed in the dark block, so no
   colour exists only in dark. */
