   FILM LAYER (dark theme only) : site-wide canvas overlay
   -------------------------------------------------------------------------
   #phosphor-fx (created by js/phosphor-fx.js) is a fixed, full-viewport
   canvas at z-index 0: above the persistent starfield, below #main (z 1),
   so every route's starfield renders through the film while all in-flow
   content, the header, and the contact band stay crisp above it. When
   the layer is live, body.phosphor-live ghosts the homepage stage
   elements and hero text to opacity 0 -- their layout, animation, and
   interactivity remain -- and the film draws them from live geometry
   instead. Light theme does not add the class. Keyboard focus on the
   ghosted mark shows an outline on the (visible) wrapper.
