When to use it
Product cards, trading card showcases, premium UI hero elements needing a luxury tactile feel.
When not to
Light backgrounds (dark gradient hardcoded). Contexts where constant motion competes with surrounding content.
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
- max tilt angle (var max=12)
- sheen gradient colors (rgba values in .c08-holo__sheen)
- foil chip colors (conic-gradient in .c08-holo__foil)
- idle drift speed (t+=0.011)
- card dimensions (46vmin/59vmin)
- theme tokens (:root dark defaults + [data-theme=light] overrides)
Keep intact
- CSS custom property tilt system (--c08-rx/--c08-ry/--c08-sheen)
- IIFE wrapper
- visibilitychange stop/start
- prefers-reduced-motion guard
- 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 dark gradient is hardcoded in body CSS — must edit to use on light pages
- Sheen uses mix-blend-mode:color-dodge which may render differently on non-dark backgrounds
- 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.
