Imagery treatment pack

An imagery treatment pack ships filters, overlays, and crop rules that make a tenant's uploaded photos feel cohesive. The runtime applies the active treatment to every image widget without the designer or tenant needing to touch a photo editor.

Key contracts

• Treatments are parameter-driven. A filter is { saturation: 0.85, contrast: 1.05, grain: 0.04 }, not a CLUT.
• Crop rules declare aspect ratios + focal-point heuristics (e.g. "if a face is detected, anchor on it; otherwise center").
• Theme-token aware. Overlay colors reference theme.color.* tokens.

cd my-imagery
vincia preview
vincia publish --dry-run

Approval gates

1. Schema parse. 2. Bounded parameters — saturation/contrast stay within publishable ranges. 3. Preview present — preview/before-after.png exists and is ≤ 1 MB.
