/* THE STUDIO KIT (17 Oct 2026). Every page (pages/*.js) and tool (tools/*.js)
 * is built from these and from studio.css's own: st-btn (primary, big, ghost,
 * danger), st-chip(s), st-q (a label over an input), st-group (a card),
 * st-toggle (iPhone switch), st-choice (a big tap card in st-add-choices),
 * st-label, st-muted, st-error, st-actions, st-pick/st-pick-one (pictures to
 * choose), st-x (close). Colours only from the variables (--bg, --surface,
 * --surface-2, --line, --text, --muted, --green, --green-ink, --gold).
 * A page's own extra CSS goes in pages/<name>.css or tools/<name>.css, every
 * rule starting with that page's own class, loaded by the module itself. */
