/*
 * Brikwall site, v2.
 * Foundation: the EDDY template system (fluid --u scale, 12-column grid,
 * masked line reveals, letter preloader with curtain + logo FLIP, rolling
 * button labels). Surface: an instrument-panel look in the spirit of
 * shift5.io (charcoal field, steel panels, mono readouts, numbered status
 * lists, a live data grid, film grain).
 * Inline styles are blocked by the CSP, so every visual lives here.
