   ENCODEX — shared content-page chrome (MONOLITH v6.0)
   ---------------------------------------------------------------------
   The landing (index.html) carries the live Sentinel Studio scene and
   keeps its chrome inline. These interior pages (services / projects /
   lab / contact) are lightweight documents that must read as the SAME
   site: identical tokens, top bar, frosted menu and status bar, minus
   the Three.js weight. A flat CSS backdrop stands in for the room.

   Transition-ready: cross-document View Transitions are opted in below,
   and the persistent chrome (bar top, bar bottom, brand) is named so a
   navigation holds it still while the content cross-fades. Build the
   bespoke motion on top of these hooks.
   ===================================================================== */

/* ---------------------------------------------------------------------------
   Lens vignette — the composer grade's, restored.
   The film stack (src/Post.js) closed every shot with an elliptical vignette:
       vec2 vc = fromCenter * vec2(1.0, 1.35);
       col *= 1.0 - smoothstep(0.14, 0.68, dot(vc, vc)) * uVignette;   // 1.2
   Dropping the composer for the direct ACES path (src/DirectPost.js) dropped
   it too. It is the one grade element reproducible EXACTLY in CSS: a plain
   multiply toward black on already-tonemapped sRGB, which is algebraically
   what an rgba(0,0,0,a) layer does — so a = 1 - vig, sampled off the real
   curve (max error 1.13/255).

   Radii are explicit percentages, NOT farthest-corner: the GLSL works in raw
   uv, so its ellipse is fixed in uv space and stretches with the viewport
   (px ratio = 1.35 x aspect). Percentages resolve x against width and y
   against height, which reproduces that at every aspect; farthest-corner
   would use W/H and lose the 1.35 vertical squeeze entirely.
   The 87.49% -> 100% solid pair is load-bearing: 1.2 x smoothstep saturates
   before the corner, so the outer diagonal really is flat black.

   Composited into each page's EXISTING scrim layer stack — no extra element,
   no extra compositor pass.
