Conflict only in docs/parity-checklist.md: the generated summary is
refreshed with `cargo xtask parity --write`, and the Last updated line
keeps main's format with this PR's change note (today's date) instead of
the duplicated note the branch carried. ⌥-drag preview still wins over
AllMasks and the selected mask in view_overlay; overlay kinds 6–9 unchanged.

Holding ⌥ (Option) while dragging a slider shows a diagnostic view in the loupe, as in
Lightroom; releasing ⌥ or the slider brings the photo back and nothing is saved:
- Blacks: shadow clipping (white; black where every channel is 0, the colour of the
unclipped channels where only some are).
- Whites / Exposure: highlight clipping (black; white where every channel is 255, the
clipped channels' colour where only some are).
- Sharpening Masking: the weight sharpening gets at each pixel, white on black.
- Sharpening Amount / Radius / Detail, luminance NR: the image in grey.
New `Overlay` variants (ShadowClip, HighlightClip, SharpenMask, Grey) are drawn by the shared
`visualize::apply`, so CPU and GPU agree; the sharpening mask needs the detail planes and
renders on the CPU (like HdrRange). The mask uses the same weight function as the render
(`finish::sharpen_weight`). With a display profile the clipping views are tested in sRGB, like
the histogram, and diagnostic views keep the photo's histogram instead of the view's.
Tracker: LR-VIEW-CLIPPING ✅ → 🟡 (J only frames the photo, it doesn't paint clipped pixels)
and LR-EDIT-DETAIL-SHARPEN ✅ → 🟡 (Radius and Detail don't reach the render).

Stacked on rb/1592: LOOK_VERSION 8 -> 9; the PR's corpus-profile helper is the base's corpus_uses_the_bundled_profile.

Resolved against rb-base-36: LOOK_VERSION 6 -> 7; starting_colour_tags passes no lens (merge frames arrive without it).

Resolved against rb-base-36: Scanned keeps the base's rewrite flag next to magic and tag; Exif keeps the Panasonic lens fallback; locale catalogs merged (one duplicate key dropped).

- Visualize HDR (#1555) has no default key: ⇧H cycles the Tool Overlay (#1473, issue #224)
- CR3 tests (#1461, #1462) accept adaptive QP 131–175, as #1694 decodes; cr3.md says the R6 Mark II files decode
- English fallbacks in the Czech and Polish catalogs use → for the menu triangle; Polish in the keyword-label test
- canvas handle tests show pins (Tool Overlay Always); a focused handle keeps its pins shown in Auto
- the model-install test and demo deadlock guards wait on deadlines long enough for a busy machine
