When to use it

Product cards, portfolio thumbnails, or any card UI where secondary text should stay hidden until the user expresses intent.

When not to

Touch-only interfaces where hover state is unreliable; also remove the auto-cycle timer before shipping in production.

Working with an AI agent

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

Adjust the existing palette tokens and effect parameters while preserving manual control. First deliberate input stops idle demo work while manual feedback finishes. Keep demo-v1 lifecycle marker, __foreverPreview.demoEnabled initialization and forever:interactive handler. Preserve reduced motion, visibility suspension and theme switching.

Safe to edit

  • panel slide duration (--dur-slow: 520ms)
  • accent gradient colors (--accent-magenta, --accent-iris)
  • panel translateY offset (56%)
  • card dimensions (48vmin / 57vmin)
  • theme tokens (:root dark defaults + [data-theme=light] overrides)

Keep intact

  • prefers-reduced-motion guard (transition-duration:.001ms)
  • IIFE wrapper
  • visibilitychange stop/start
  • :focus-within selector for keyboard access
  • theme hook (?theme= bootstrap + forever:theme message listener + theme tokens)
  • sticky demo-v1 preview lifecycle; stop attract work, retain manual feedback and settling
  • pointer/touch takeover, keyboard access and visibility suspension
  • demo-v1 preview lifecycle: initialize demoEnabled from window.__foreverPreview and stop attract work on the window forever:interactive event; retain manual feedback, settling, cleanup and explicit sessions

Known limitations

  • Background is a CSS gradient, not a real image; swap in an actual img/background-image for real content
  • Control state is local to each mount; format changes preserve preview takeover but create a fresh source instance.
  • State remains local to each mounted instance; format/theme remount preserves takeover, not component values.
