/* Public site (home, features, use cases, pricing, about, FAQ, contact, legal, errors). Loads after app.css and
   re-points its tokens, so shared pieces (menus, inputs, toasts) turn dark too. The public site is dark only.
   Direction "dark canvas": a near-black page framed by hairline column rails, a grainy teal glow behind the hero and
   the closing call to action, Geist headlines with one accent phrase in Instrument Serif italic (Vazirmatn bold in
   teal for right-to-left scripts), mono labels and pill eyebrows.
   Motion: .rv fades up once in view, the hero headline blurs in word by word, the app window flags and replaces a
   risky phrase, the statement lights up as it scrolls. All of it is off with reduced motion, and every section is
   complete without JS. Logical properties keep RTL correct. */
