chore: integrate asset-quality gate - survey worklist, sheets, regenerated pages

ROADMAP carries the full-gallery floor survey: 26 of 42 pass; the 14
below-floor entries are all contract-vehicle/display subjects with
measured numbers, none a game asset, none a remodeling mandate. Asset
sheets for both remodeled examples committed under
docs/gallery/asset-sheets/ (before/after beside the reference set).
Staging contact sheets refreshed for both heroes. gallery.json,
blender-smoke comments, and generated gallery pages updated for the moved
closed forms (21 parts/3680 islands; 20 detail/21 hygiene parts).

 - ~~Degenerate-bevel weld hazard~~ **SHIPPED** as `examples/degenerate-bevel-weld/` — at `offset == min_dim/2` the bevel band collapses to exactly 12 zero-area faces (4 min-axis edges × 3 segments) with 16 coincident verts (4 × (segments+1)) and min_area down 3.2e5×; a stdlib GLB re-parse counts **32 degenerate triangles crossing the export boundary** (MEASURED regression constant) versus 0 for the safe mesh — the loops an engine merge-by-distance welds; byte-identical on 4.5.11 and 5.1.2

 - UV atlas **utilization** witness — coverage/wasted-texel closed forms for a packed lightmap atlas (the non-overlap, unit-square, margin, and active/active_render contracts shipped in `lightmap-uv-channel`; utilization is the remaining unbuilt slice of the old "UV atlas pack" candidate)
 - ~~GAMMA_CROSS blend-curve witness~~ **SHIPPED** as `examples/vse-gamma-cross/` — the cross blends in a gamma-0.5 space: `((1-t)·√A + t·√B)²` with `t = (frame − start)/duration`, never 1 inside the effect; mid-cross dips 0.115 below the sRGB lerp from crimson/teal (closed form (0.341, 0.349, 0.463) confirmed per frame); AgX-default sampling poisons the fit (0.146 red-channel error, `view_transform='Standard'` mandatory); deleting a consumed input orphans-and-deletes the effect — follow-up to `vse-cut-list`
 - Falsy `bpy_prop_collection` trap snippet: an empty collection is falsy, so `editor.strips or editor.sequences` silently falls through to the legacy accessor on an empty timeline — always branch on `hasattr`; likely generalizes across the API (found authoring `vse-cut-list`)

 - ~~Gallery framing recomposition worklist~~ **DRAINED**: all four recomposition cases restaged and gated with `check_framing` — depsgraph-export (0.984x/touch→0.812x; cube+dome recentered, aim-based camera), vertex-weight-limit (touch B→0.867y; more frontal camera, lower aim, base in frame), triangulate-tangents (0.334x→0.833y; 2x-class move-in plus Key/Glint trim that also cleared a pre-existing dome blowout), text-version-stamp (0.663x→0.719x; moved in with aim on the stamp center, dead third gone). The seven marginal cases were camera-nudged in the preceding sweep; deviations documented in #108 (damped-track-aim, wave-displace); sky-texture-sun-elevation is a measurement artifact (world subject — report-only if wired). Remaining: nothing on the framing worklist — future examples inherit the gate at authoring time.
