Spotlight reveal

A dark panel whose details light up where a spotlight passes.

A spotlight follows the pointer inside the panel and lights up the details under it; without a pointer it drifts on its own and the arrow keys move it. The text is readable even in the dark, and reduced motion lights everything.

Try it

<spotlight-reveal>

Build me a Taggor component like "Spotlight reveal" (spotlight-reveal): A dark panel whose details light up where a spotlight passes. Fetch https://taggor.dev/agent-setup/prompt.md and follow its instructions to set me up for Taggor. Ask me before you sign in, create an account, accept terms, pay for anything or type a secret. Check it with `taggor check` and publish it with `taggor publish`, and stop there. Do not promote it to production, attach it to a site, roll back anything or use --yes, --force or --force-drop-invalid unless I ask for exactly that in this conversation.
