   MYSTIC GLITCH LABS  --  tactical HUD
   --------------------------------------------------------------------------
   Layer stack, back to front:
     0  body            near-black teal base + deep-blue bloom (static gradients)
     1  .bg__grid       perspective city grid, fading toward a horizon
        .bg__haze       cyan/magenta light pooling on the horizon
     2  .bg__skyline    pixel-window skyline (inline SVG) with neon signs that
                        dip once every few seconds
     3  .bg__rain       vertical glyph rain (inline SVG: katakana-like strokes
                        + arcane runes drawn as paths, no font dependency)
     4  .hud            header landmark: two status corners
        .stage          hero copy (left, on a scrim) and the figure (right):
                        spell-circle HUD, thermoptic ghost copy, portrait,
                        glitch-tear copy, targeting frame, scan line, labels
        .foot           footer landmark, bottom-left
     5  .fx__camo       thermoptic-camo pixel bands sweeping over everything
     6  .fx__scan       static scanline texture + vignette
   Motion is transform / opacity / clip-path only. Under prefers-reduced-motion
   every animation is switched off by name (see the end of the file) and the
   composition stays intact.
