A House Drawn
By First Light

Build a full-screen architectural landing page driven by one continuous camera move.

Sequence
- Generate one still: a close view of the facade with a window that shows the room inside. Every other view grows from this still, so the whole page stays one place.
- For the opening, generate a video from the facade still alone with the camera flying backward, then reverse it. The wide view and the facade are then the same scene, with no morph.
- For the room, generate a second video from the same still alone, with the camera pushing through the glass and into the room. Do not join two separately generated stills: they will disagree on roof, light and materials.
- Pick a frame from that push that composes well and redraw it with image-to-image at about 0.6 strength to recover detail. Then regenerate the push as a first/last-frame video from the facade to that frame, and export both shots as WebP frames.
- Pin a canvas to the viewport inside a scroll track. The wheel decides which frame shows, in both directions, so nothing moves while the wheel is still. Do not autoplay the video.
- Add wheel distance to a target and follow it with a critically damped spring. When input stops between chapters, settle on the next chapter in the direction of travel. Keep native scrolling for keys, the scrollbar and touch.
- Export every video frame and blend the two nearest frames on the canvas, so slow parts of a move do not step.
- Load every sixteenth frame first and fill in the gaps, drawing the nearest loaded frame so a fast scroll never shows a blank canvas.

Chapters
1. Left-aligned light headline with a thin rule, one sentence and two actions.
2. Large rotated headline, one inset material detail, a row of material swatches and one action.
3. Large white headline, colour swatches on the left, a short note and the final action on the right.

Behaviour
- Fade each chapter's text in and out around its rest position, and keep hidden links out of the tab order.
- Use a smaller, shorter frame set on phones, with text over a bottom scrim.
- With prefers-reduced-motion, snap to the nearest still instead of scrubbing.
- Keep a static poster behind the canvas as the first paint and the failure state.
