# Night Shift Direction
## Chosen direction
- Treat the page as a quiet night field guide: one image is the instrument, and the interface behaves like a page marker around it. The first screen is dark enough for the image's stars to remain visible, but the type is warm and paper-like rather than a generic neon space dashboard.
+ Treat the page as a quiet night field guide: two image records are the instrument, and the interface behaves like a page marker between scales. The wide DSS2 field establishes context; the Hubble ACS observation resolves the encounter. The first screen is dark enough for the material to remain visible, but the type is clear and restrained rather than a generic neon space dashboard.
## Alternatives
- A dense observatory dashboard: useful for repeated measurement, but it makes a single astronomical image feel like a data tile.
- A cinematic full-screen space poster: memorable, but it hides the actual reading task and source trail.
- - A field guide with changing reading distances: chosen. It gives the real M51 image an authored sequence and leaves room for facts, controls, and provenance.
+ - A field guide with two source scales: chosen. It makes the wide field and Hubble detail materially distinct while keeping the same M51 encounter, facts, controls, and provenance visible.
## Material decisions
- - `m51-galaxy.jpg` is the visual protagonist. Its wide-field view, companion, and core remain inspectable at different reading distances.
- - Sora handles navigation and measurements; Newsreader handles the essay line and object title.
- - Warm white, mineral green, and a small amber signal are derived from the image rather than a purple space gradient.
- - Grouping uses spacing, tone, and a few soft circular markers. Repeated cards, decorative star fields, and fake telemetry are rejected.
- - The zoom-like transition has a purpose: it changes how the visitor reads the same real image. Reduced motion keeps the final view and the controls usable.
+ - `m51-galaxy.jpg` supplies the wide DSS2 field and `m51-hubble.jpg` supplies the Hubble ACS pair/core view. Each image keeps its own record and credit.
+ - Sora handles navigation and measurements; Newsreader handles the field note.
+ - Paper, ink, blue, and coral are derived from the inspected Hubble image rather than a purple space gradient.
+ - Grouping uses open image stages, spacing, tone, and named feature markers. Repeated cards, decorative star fields, and fake telemetry are rejected.
+ - The view transition has a purpose: it changes the scale and material of the observation. Reduced motion keeps the final view and controls usable.
