   hugonarciso.net — shared chrome for hosted games
   Injected into every /projects/<slug>/index.html by
   scripts/sync-games.mjs (between hn:vt markers). Provides:
   1. the cross-document view-transition opt-in,
   2. the persistent site topbar (pairs with the portfolio nav),
   3. the "card unfolds into the game" choreography.
   Everything is px-based so per-game root font sizes can't skew
   the topbar geometry (it must match the portfolio nav 1:1).
