/*
 * appcore web shell styles (spec §13, brief item 13).
 *
 * Scoped under #app-shell and built on the shared site tokens that every
 * product page already loads (site.css + the generated theme.css):
 *
 *   --ink --wash --paper --flag --flag-ink --flag-wash --ok --line --muted
 *   --font-head --font-body --radius --radius-small
 *
 * Each is read once, at the top of #app-shell, into a private --s-* token with
 * a fallback, so the shell also works on a page that loads none of them. The
 * older --app-* properties still win when a page sets them:
 *
 *   --app-ink --app-bg --app-wash --app-accent --app-font
 *
 * The signed-in email link renders into `[data-app-shell="auth"]` elements
 * that live OUTSIDE #app-shell (the page header hosts it), so its classes
 * (.app-shell-auth-link, .app-shell-auth-btn) read the same tokens with the
 * same fallbacks.
