When to use it

Ambient backgrounds for Japanese-aesthetic projects, portfolio headers, or calm looping screensavers on dark-themed pages.

When not to

Light backgrounds (sky hardcoded cream/navy). Contexts where moving rain competes with legible text overlays.

Working with an AI agent

Every component ships agent-ready metadata. An example instruction for this one:

Increase rain streak count to 150 by changing N=96 to N=150, shift the rain to a warmer white by changing RAIN to "#f5e8d0", and slow fall speed by changing rs[i]=0.45+Math.random()*0.55 to rs[i]=0.25+Math.random()*0.35. Theme: dark tokens live in :root, the light variant in :root[data-theme="light"]; ?theme=light or a {type:'forever:theme'} postMessage switches at runtime.

Safe to edit

  • rain count (N=96)
  • rain slant (SLOPE=0.34)
  • rain color (RAIN variable)
  • fall speed range (rs[i] = 0.45+random*0.55)
  • hill band positions (H*0.50..H*0.80)
  • palette constants (SKY_TOP, CORAL, HILL1, etc.)
  • theme tokens (:root dark defaults + [data-theme=light] overrides)

Keep intact

  • IIFE wrapper
  • prefers-reduced-motion static frame guard
  • visibilitychange stop/start
  • DPR-aware canvas resize
  • theme hook (?theme= bootstrap + forever:theme message listener + theme tokens)

Known limitations

  • Background and sky colors are hardcoded — must edit palette constants to change overall tone
  • Village roofline positions use deterministic pseudo-random math — altering M changes the silhouette unpredictably
