/* YIC UI primitives: the one shared set of building blocks for the member app.
   Read docs/UI_PRIMITIVES.md first: it is the API (class names, markup, states)
   and says which existing screens each primitive was lifted from.

   Rules of this file
   - Everything is namespaced yic-*, so it can load beside the app's own CSS
     (member-mobile-*, mobt-*, ...) while screens migrate one at a time.
   - It looks IDENTICAL to what ships today. The SPA primitives (button, segmented
     control, row/list, panel, chip, eyebrow, stat, sheet, switch) are lifted from
     the phone app's own rules, selector for selector. The standalone-page pieces
     (field, notice, mark, the metal and pill button faces) are lifted from
     login.html, join.html, rsvp.html, checkin.html and install.html.
   - Where today's screens disagree with each other (three gold buttons, four
     golds), the differences are kept as NAMED variants and skins below, never
     silently merged. Merging them is a visual decision for the owner.
   - No glows under buttons, no glass blur (owner rules).
   Loaded as /public/yic-ui.css by the standalone pages. */
