coaurora 0.1.0

First release.

A WebGL aurora background that is, internally, a Store comonad.

• Two-pass GPU pipeline: extend curtains → texture (the Store, materialised) → extend blur → extend dither → extract
• TPDF blue-noise temporal dithering — band-free gradients on 8-bit displays
• Canvas-2D fallback with the comonad spelled out (Store / extract / extend / seek)
• Zero dependencies, ~10 kB, ESM + TypeScript types
• Live demo & playground: https://jagajaga.me/coaurora/
