TITLE: Frost Garden — Diffusion-Limited Aggregation FILE: 037-frost-garden.html === PROMPT (exact prompt used) === Build "Frost Garden — Diffusion-Limited Aggregation", a crystal-growth simulation that produces delicate branching ice and coral structures. A canvas with a deep blue-black gradient (#020617 → #0b1d3a). Random walkers diffuse and stick when they touch the growing cluster; stuck particles are coloured by arrival time (pale ice #e0f7ff through cyan #67e8f9 to violet #a78bfa) with a soft glow, so the structure looks like frost lit from within. Use an efficient approach (spawn walkers near the cluster radius, grid occupancy, many steps per frame) so growth is visibly lively. Modes: "Point seed" (radial frost), "Line seed" (frost growing up from the bottom like on a window) and "Snow" (6-fold symmetric growth). Interaction: click to add seed points; a stickiness slider (branch density); speed; palette (Ice / Coral / Gold filigree); pause; download. A subtle particle count and elapsed time in elegant monospace. Title in thin, widely spaced capitals. SHARED REQUIREMENTS (apply to every page in this 100-page collection): 1. One standalone HTML5 file. All CSS inline in
