fix: vse-cut-list quality pass

[TMHSDigital]

Quality pass on vse-cut-list, a Track B example: the contract is frozen, and only the staging of the editing bay changes. The binaries were .scratch/blender-4.5.11-windows-x64 (reports Blender 4.5.11 LTS), blender-5.1.2-windows-x64 (Blender 5.1.2) and blender-5.2.1-windows-x64 (Blender 5.2.1 LTS). The hero was rendered on 5.2.1 through scripts/render_hero.py. The inspection sheets (hero angle, clay three-quarter, wireframe, per-object close-ups, ground contact) come from the example's own Bay scene via its framing call and stayed in .scratch/.

Picks: every showcase piece and every check-only example has already had a pass. I inspected three unreviewed gallery examples and only one had a defect worth fixing:

• vse-cut-list: fixed below.
• png-exr-alpha: both displays stand on struts in a plinth, captions are legible, ground contact is sound. No change.
• socket-attach-points: a hovering drone with its skid clear of the floor, every part attached, framing ok. No change.

vse-cut-list (Track B)

Defects (round 0):

1. The monitor neck's top face (z 1.24) sat exactly on the bezel's bottom face, a butt joint on one plane with no bite. Half the 0.12 m neck hung out behind the 0.09 m bezel. Seen in the clay three-quarter and the wireframe.
2. The stand base sat exactly on the desk top, another coplanar contact.
3. The "PROGRAM" caption lay flat on the desk top, floating 6 mm above it, and read as a smear at the camera's grazing angle. Seen in the hero and close_5_BayCaption.

Presentation changed: the part heights are now derived from named constants in the order they stack. The base bites the desk top by 5 mm; the neck starts inside the base and ends 0.10 m inside the bezel; the neck's depth (0.07 m) sits within the bezel's depth, set 0.02 m back. The caption stands upright on the desk's front face, set 1 mm into it. It is the same text curve with the same body, so nothing the example asserts about text strips is involved.

Contract unchanged: the sequencer frame on the screen is still the genuine rendered output. Every check and exit code is untouched, and the check line printed before and after is identical.

	4.5.11	5.1.2	5.2.1
before: default / --swap-inputs / --output	0 / 7 / 0	0 / 7 / 0	0 / 7 / 0
after: default / --swap-inputs / --output	0 / 7 / 0	0 / 7 / 0	0 / 7 / 0

Framing on the render path: fill y 0.850, minimum margin 0.067, ok.

Contact sheet

vse-cut-list: luma 0.2215, stage 0.195, warmth +0.018, saturation 0.10. All are in family and essentially unchanged from the old hero (0.2214), since the edit is small and local. Legible at thumbnail size, and the caption now reads.

Checks run locally: check_exit_code_readme.py and check_gallery_images.py pass. I read the generated alt text in docs/gallery/index.html and docs/gallery/vse-cut-list/index.html.
