/* ThinkTorch public landing — a committed dark "operator's console" world.
   Everything is scoped under .tt-landing so it can't leak into the authenticated
   MudBlazor app. Single-theme by intent: the landing paints its own ground and
   colours from tokens, independent of the app's light/dark MudBlazor theme.

   The hero's dependency-chain "ignites" on load via CSS animation only (no JS),
   which is robust under Blazor Server's prerender + circuit reconnect. The final
   lit state is the DEFAULT styling, so reduced-motion and no-animation users see
   the correct end state; the animation just replays the sequence for everyone
   else. */
