# Version0003 browser review

Reviewed in the local in-app browser at desktop1280×720 and mobile390×844 before freeze, with no console errors in the reviewed flows.

- All four licence terrain presets displayed the local DSM and satellite texture. Final lighting was reviewed at true elevation scale. Source acquisition dates, EGM2008 height ranges and geographic registration limits remained visible.
- ULG Original/Compare/Native, reconstructed geology, historical evidence, licence filtering, Top/Spatial, Fit and zoom were exercised. Camera zoom persisted across reload (359 source pixels before and after). Old scene identifiers remain declared and their referenced assets resolve.
- Feature search and list selection, selected-layer isolation and restoration, and RC27 depth-column selection were checked. RC27 shows15.5–17.5m,2m at215ppm eU3O8. The five columns share a depth scale and do not imply total depth or blank/unsampled intervals are barren.
- Mobile body width equalled390px without horizontal page overflow. Expanded licence/target selectors and close control were visible. The terrain viewport supports scrolling to supporting controls and evidence notes.
- Explicit graphics-off fallback retained the warning,64 selectable ULG feature-list entries, source links, native SVG link and five depth columns. Static narrative and catalogue remain in the HTML. Downloads and230 linked local assets returned HTTP200 in the independent structural check.

Limits: this is a browser/UI review, not survey certification or geological validation. Physical trackpad/pinch gestures and real mobile hardware were not tested. Selection was verified through accessible controls; no claim is made of exhaustive pixel-by-pixel canvas picking. Source-local feature geometry was reviewed separately against its original in geometry-review-v3.json. The source-image checklist records partial extraction and unreadable/omitted content.
