   LANDING PAGE (.lp) — dark-first marketing surface
   ───────────────────────────────────────────────────────────────────────────
   Tokens are scoped to .lp so the authed app keeps its own Material 3 theme
   untouched. Dark is the DEFAULT here (the app itself follows the OS
   preference); light applies only when the visitor explicitly picks it via the
   nav toggle, which sets html[data-theme="light"] through toggleTheme() in
   ui.js — the same switch the rest of the app already uses.
