Joel Brock 1346f7a40c Add Singularity template: WebGL nebula + holographic cards ...

Third theme template scoped to :root[data-template="cosmos"], joining
editorial and swiss. Set "theme.template": "cosmos" in links.json to
activate.

Background — full-viewport WebGL fragment shader running a 5-octave
warped fBm nebula in indigo/violet/magenta/cyan, with a two-layer
procedural starfield (small dense + sparse blue-white halo) twinkling
on independent phases. Pointer-tracking gravity well subtly perturbs
sampling around the cursor. Pixel ratio capped at 1.5x for fill-rate;
loop pauses on visibility change.

UI — Orbitron display + Geist body, glassmorphic cards with
backdrop-filter, conic-gradient holographic borders driven by
@property --cosmos-hue rotating on hover, gradient-clip section
numbers and project titles, chromatic-split hero last name on hover
(::before + ::after pseudos with mix-blend-mode screen using a
data-text attr), glowing drift-orb in place of the editorial asterism,
animated section-head accent line.

Fallbacks — prefers-reduced-motion or WebGL-unavailable triggers the
.cosmos-static class with a CSS-only radial-gradient nebula and all
heavy animations disabled. Always-dark regardless of theme toggle.

README documents the new template; links.example.json unchanged.
