Buffering

Video-stream buffering bar: a sage-green fill chases a buffered-ahead band with a sweeping sheen, 8 segment dots, live percent counter, and ETA readout.

When to use it

Loading screens, video player buffering states, file upload or download progress indicators with a premium dark-UI feel.

When not to

Light-background UIs (background is hardcoded dark navy). Contexts needing real progress data — requires wiring real values to the paint() function.

Working with an AI agent

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

Change accent color to electric teal by setting --pg09-ac to #00c4b4 and --pg09-ac2 to #5ffff0, and slow the cycle to 10 seconds by changing cyc=7 to cyc=10. 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

  • accent color (--pg09-ac, --pg09-ac2)
  • segment dot count (NSEG=8)
  • notional clip length for ETA (TOTAL=12)
  • cycle duration (cyc=7)
  • sheen sweep speed (t*0.55)
  • theme tokens (:root dark defaults + [data-theme=light] overrides)

Keep intact

  • IIFE wrapper
  • prefers-reduced-motion guard with static fallback
  • visibilitychange pause/resume
  • aria-progressbar role + aria-valuenow updates
  • theme hook (?theme= bootstrap + forever:theme message listener + theme tokens)

Known limitations

  • Simulated progress only — must replace prog/bufd logic with real data for production use
  • Light re-theme via the [data-theme=light] token block; catalog bg/accent describe the dark default
