Fork of the santafe.live "Image Cache Manager" adapted for AlertWildfire/AlertCalifornia PTZ cameras: thumbnail **grid** + 2D map + **3D map** views over a timeline zoomed to the imagery date-times, with per-image pose/time **sidecars** derived from camera telemetry. **Read order:** [about.md](about.md) (canonical entry) → [2026-06-13/notes/00-design-questions-and-vision.md](2026-06-13/notes/00-design-questions-and-vision.md) (sidecar recommendation, catalog-management vision, open questions) → `repo/` (the app, once built). Status: hatched 2026-06-13; planning gated on open questions. See [about.md](about.md).
