/* ===== Landing page (loaded only by common/landing.html) =====

   Three blocks — hero scene, the three-principles module, Telegram.
   Everything is scoped under body.landing-page so the app shell's own
   tokens/components in base.css stay untouched. Theme overrides mirror
   base.css's precedence: light default -> OS preference -> explicit
   html[data-theme] toggle.

   Visual rules: blue is a UI accent (buttons, counters, links), never a
   light source — no glows, haze or gradient fog. Surfaces are flat,
   slightly lifted from the background, separated by thin borders. */
