The preceding OGL-based revision is pinned because commit 482ab1c changes the
renderer to a different WebGL2 API. This website adapts the OGL version.
Changes: independent JavaScript lifecycle, two shader layers, finite-distance
guards, defined smoothstep edges, coordinated color and motion, capped DPR and
400,000-pixel budget, 30 fps draw budget, adaptive quality, offscreen/hidden-tab
pause, static fallback, a persistent shared-layout spiral mesh with curved-path
arrival, a five-color star palette, local-preview replay and a reveal uniform.
Site-specific additions include generated gas/dust, spatial cloud condensation,
a shared four-minute disk rotation, and a separate softened pointer lens with
a 260 CSS-pixel falloff applied to the combined gas and star image.
This is part of this website, not a standalone component.

Existing Regular and Bold TTFs were converted to WOFF2 and split by Unicode
coverage without changing glyph outlines. Modified fonts use the internal
family name HBL Neo Web; NanumSquareNeo is the website's CSS family alias.
Regeneration script: scripts/create-neo-fonts.py. All original Unicode glyphs
remain available across Latin/symbol, common Hangul and extended Hangul subsets.

Research diagrams, star background, interstellar cloud texture, favicon and social card
Created for this website. Research diagrams are conceptual illustrations,
not model outputs or measured results.
The cloud texture is deterministically generated by scripts/create-nebula.mjs.
The softened point-lens effect is a decorative approximation, implemented for
this website; it is not a scientific ray-tracing or astrophysical simulation.

The body cursor light, repeat entrances and arrival policy were implemented
specifically for this website, without Three.js or another animation library.
