/* The OneEPC landing page (issue #110). One file, no build step.

   Keep in step with src/styles/tokens.css: every `--ui-*` below is copied
   from there by name, because this page is served outside the bundle and
   cannot import the token sheet -
     --ui-font, --ui-font-mono, the @font-face block (the woff2 files are
     the bundle's own, linked from /app/fonts/),
     --ui-bg, --ui-surface, --ui-hairline, --ui-ink, --ui-ink-muted,
     --ui-action, --ui-action-hover, --ui-action-ink, --ui-focus,
     --ui-brand (= --ui-action), --ui-brand-ink (= --ui-ink),
     --ui-brand-dim (= --ui-ink-muted),
     --ui-text-body / -strong / -mark,
     --ui-weight-regular / -medium / -semibold, --ui-tracking-mono,
     --ui-leading-tight / -text, --ui-space-3 / -5 / -7 / -8, --ui-radius,
     --ui-border, --ui-h-control-lg, --ui-focus-ring.
   The `--landing-*` tokens are this page's own: the lockup is a hero here,
   not a 60px band's head, so its sizes have no counterpart in the app. The
   literals are the wordmark's `line-height: 1` (as `.ui-brand__word` in
   components.css) and the two breakpoints - the shots stacking, and the
   phone - which a custom property cannot express in a media query.
   Logical properties only: the page is dir="rtl" and the two Latin lines
   flip to LTR with `.ui-ltr`, the same class the app uses. */
