Title: Scroll Progress Tale — The Lighthouse Keeper
Prompt: A five-chapter lighthouse story where scrolling is the voyage. A striped tide rail fills overhead while a tiny ship sails with the reader past arrival, storm, garden, night, and dawn. Each chapter has its own arched illustration and small task.
Design: Parchment long-form tale with alternating illustration and prose chapters, arched lighthouse scenes with sweeping beam and sliding wave keyframes, chapter jump nav, and a stamped finale log.
Visual techniques:
- Scroll-driven striped progress rail with sailing ship marker
- Rotating beam sweep and sliding wave keyframes
- Intersection-triggered chapter reveal transitions
- Scroll-mapped lamp opacity for storm feedback
- Responsive alternating chapters with dashed separators
Interaction model: Scrolling drives rail, ship, reveals, and finale stamp; buttons jump between chapters, plant persistent seeds, summon squalls, copy keeper lines, and a three-tap signal game logs rhythm accuracy.
