Settings (Cmd+, / app menu on macOS, Edit elsewhere) with General, Import,
Performance and Interface tabs. App settings (startup view, delete
confirmation, GPU, preview size, filmstrip/grid badges, last library) live in
UiState.settings (ui.json); library settings (raw / non-raw / per-camera
import presets, XMP, thumbnail cache size) go through library.preferences into
prefs.json. Import applies the matching default preset; the photo remembers it
as its import look (unedited; Reset returns to it). Open Library… switches
libraries at runtime.
View modes: F full-screen preview (photo on black, arrows step, I cycles the
info overlay, Esc exits), Cmd+Shift+F window full screen, Cmd+I cycles the
loupe info overlay (off / file + date / exposure), Navigator mini map while
zoomed (click/drag pans).

Auto uses Upright's consensus level angle as the crop angle; sign verified on a tilted test image
and pinned by a test.

- pipeline::upright: own gradient-based line-segment detector (level-line region growing seeded from the
strongest gradients, weighted principal-axis fit, elongation test); vanishing points by RANSAC over
segment pairs + least-squares refinement (smallest eigenvector of Σ w·l·lᵀ)
- corrections as a virtual camera rotation K·R·K⁻¹ (vertical VP → y axis; Full also horizontal VP → x axis
with focal length from VP orthogonality when plausible); Level = rotation; Auto = Full/Vertical when
moderate, else Level; all re-centred
- Guided: guides stored in normalized lens-corrected coordinates; 2+ vertical/horizontal guides define the
vanishing points, a single guide levels
- the analysis runs on the lens-corrected image at 1024 px and the result is stored in
geometry.upright_transform (identical preview/export); settings naming a mode without a transform
(XMP, CLI) are resolved at render time
- commands geometry.upright {mode} (Update = run again) and geometry.guides {guides, add}
- UI: Upright mode buttons, Update, Draw/Clear Guides in the crop panel; on-canvas guide drawing that
follows the warp
- tests: segment detector on known lines; Vertical/Auto/Full fix converging verticals; Level fixes a tilted
horizon; Full fixes both families; guided from two guides; analysis resolution independence; lazy vs
stored transform; engine commands
