Title: Tooltip Planetarium — Hover the Sky
Prompt: A dark planetarium dome where seven glowing stars drift on dashed orbits, each hiding a dossier tooltip with distance and lore. Visitors hover or keyboard-focus stars to open dossiers and pin favourites into an observation journal. Midnight, gold, and ice-blue styling.
Design: Split sky-and-docent layout with gradient dome, dashed orbit rings, twinkling star buttons in gold, ice, and rose variants, edge-aware dossier tooltip card, and journal ledger below.
Visual techniques:
- Twinkle scale keyframes with adjustable duration
- Slow orbit rotation and radial nebula washes
- Edge-aware tooltip placement flipping above or below
- Focus-visible keyboard dossiers plus Escape dismissal
- Responsive dome-to-stack layout with legend chips
Interaction model: Hover or focus opens a dossier after the chosen delay; Pin adds the star to the journal with counts; twinkle slider retunes animation; Escape or leaving the dome closes the tooltip.
