/*
  Val Davis: design tokens and component primitives.

  The primitives follow the behaviour and structure of shadcn/ui (MIT, https://ui.shadcn.com), which
  builds on Radix UI (MIT): Button variants, Badge, Separator, Skeleton, Sheet, Dialog, form fields with
  inline errors, Alert/Toast, Toggle group. They are ported by hand to plain CSS and vanilla JS
  (public/js/components.js) and restyled for a quiet gallery: hairline borders, 0-2px radii, no heavy
  shadows. The private studio (studio.css) uses the same tokens with a softer, more app-like finish.
