/* The public landing page (Components/Pages/Landing.razor). One set of tokens, light and dark like the app: the
   device decides unless the visitor chose (data-theme on <html>, set by landing-theme.js). The base accent is the
   app's default look (Ledger navy). Five designs take turns per
   visit (.lv1 … .lv5); each sets its own type and accent on the shared tokens. No web fonts: the page loads fast. */
