Cursor & Pointer

Spotlight Mask

Radial spotlight follows the pointer, punching through a dark veil to reveal a pink dot grid and glowing word. Auto-demos via Lissajous path until first deliberate input.

When to use it

Dark-theme hero sections, teaser/reveal interactions, portfolio landing pages that want cursor-driven drama.

When not to

Light backgrounds (veil color hardcoded dark navy). Contexts where cursor visibility matters — cursor is hidden inside the canvas.

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. Arrow keys steer; first click/touch stops the attract path permanently for this mount. Keep demo-v1 lifecycle marker, __foreverPreview.demoEnabled initialization and forever:interactive handler. Preserve reduced motion, visibility suspension and theme switching.

Safe to edit

  • revealed word (WORD variable)
  • accent color (ACC='#ff5ca8')
  • spotlight radius scale (base = min*0.22)
  • lerp spring speed (k=0.18 pointer / 0.085 demo)
  • dot grid density (gap = min/16)
  • theme tokens (:root dark defaults + [data-theme=light] overrides)

Keep intact

  • evenodd arc clip for outer veil
  • DPR-aware canvas sizing
  • visibilitychange pause
  • prefers-reduced-motion static fallback
  • 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

  • Light re-theme via the [data-theme=light] token block; catalog bg/accent describe the dark default
  • cursor:none hides the system cursor inside the tile — must restore in production wrappers
  • Dot grid loops over full canvas each frame; dense grids on large screens may drop frames
  • 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.
