Chevron March

Interlocking gold and ink chevron bands march in alternating directions across a black canvas; a convoy of gold diamonds glides down a central seam.

When to use it

Art deco hero backgrounds, luxury brand splashes, ornamental loading screens with a black-and-gold palette.

When not to

Light-background UIs — background is hardcoded near-black. Contexts requiring legible text overlays due to constant band motion.

Working with an AI agent

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

Change GOLD to '#c9a84c' and GOLDHI to '#ffe066', increase baseSpeed multiplier from 0.10 to 0.18 for a faster march, and raise diamond count dn from 7 to 12. 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

  • gold palette (GOLD, GOLDHI, GOLDLO constants)
  • march speed (baseSpeed = W*0.10)
  • band height ratio (H/9)
  • diamond count (dn=7) and size (bandH*0.30)
  • chevron amplitude (bandH*0.85)
  • theme tokens (:root dark defaults + [data-theme=light] overrides)

Keep intact

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

Known limitations

  • Background color hardcoded in CSS and BG constant — must change both to alter background
  • Gradient objects (goldGrad, inkGrad) are rebuilt on resize but not on palette changes at runtime
  • No pointer/click interactivity — purely passive
