/*
 * Prism — main stylesheet.
 * Design tokens use space-separated "R G B" triples. Always consume them
 * with the modern `rgb(var(--x) / alpha)` slash syntax — the old comma-style
 * alpha function (with an "a" suffix) is invalid here and gets silently
 * dropped by the browser.
 *
 * Palette: a true near-black studio base (void/charcoal) — the hero's
 * light-dispersion effect (a real Cauchy-dispersion, Snell's-law prism
 * spectrum) needs genuine darkness to read, the same principle Argon's
 * neon glow relied on. The full spectral rainbow is available as an accent
 * system, but used with restraint: three "hero" accents pulled from the
 * spectrum — a violet/magenta, a cyan, and a warm amber — carry every CTA,
 * link, and highlight; nothing else in the UI reaches for a rainbow.
 *
 * LEGIBILITY: every content block that sits over the persistent GPU canvas
 * carries its own solid/semi-opaque scrim (rgba void + backdrop-filter
 * blur) so text stays legible regardless of what the shader is doing
 * behind it at that scroll position — this exact class of bug hit the
 * immediately-prior Argon build and had to be patched after the fact.
 *
 * Type scale: perfect-fourth 1.333 ratio, 7 sizes (the same ratio this
 * theme's own type-scale tool defaults to). Spacing: the same 4px-based
 * scale used across the catalogue (8/12/20/32/56/96). Headings use
 * Instrument Serif (idiosyncratic display serif, real typographic
 * character); body copy uses Manrope (clean geometric workhorse sans).
