Began reverse engineering the wretox 2d canvas UI this evening; this'll take some more effort than I thought.
The hero animation is rendered on a single using the plain 2D Canvas API (getContext('2d')) and requestAnimationFrame, all driven by one Astro‑bundled module: /_astro/index.astro_astro_type_script_index_0_lang.DqrPRLs3.js (~14 KB minified).
The bundle's option schema is fairly distinctive though — its config object exposes:
particles: generationType, ppm, max, maxWork, connectDistance, relSpeed, relSize, rotationSpeed, color
mouse: interactionType, connectDistMult, distRatio (this is the part driving the high‑performance pointer interaction — proximity‑weighted line linking + an attract/repel force based on interactionType)
gravity: repulsive, pulling, friction, maxVelocity (a lightweight verlet/Euler integrator: each frame applies repulsive + pulling forces scaled by Δt, clamps to maxVelocity, then damps with friction)
So, I think I can shoehorn revitalized, non-focal grounded (blobwise only) gravity vectors and 2d IO as well as the accel stack within this boundary for some jovial golfing, but tbh I had hoped this was some neat pre-existing system from which to iterate.
