/* ─────────────────────────────────────────
   SECTION — RSVP PAGE (rsvp.html), option C
   A photo on the left (sticky on desktop) with the deadline and a countdown;
   the form on the right. One set of fields per person (.rsvp-person);
   "Add another person" (js/rsvp.js) adds the next set.

   Choices are real radio buttons and checkboxes (keyboard + screen readers),
   drawn as options: the picked one is filled clay with a cream tick, the
   others stay outlined; the focused one gets a clay ring.
   Text styles live in foundations/text-styles.css.
