Byte preservation
The packaged file must match the protected digest exactly. Re-encoding, cropping the source file, recoloring, filtering, or replacement fails the release gate.
Visual and interface evidence
Protected visual integrity.
The approved Concresca hero image must remain byte-identical, visibly rendered, semantically present in the document, and usable across desktop and mobile layouts. A CSS cache, opaque overlay, missing path, or redesign may not silently remove it.
Canonical visual
One protected file. No substitute.
The current owner is /assets/brand/concresca-hero-approved.png. Its expected SHA-256 is d1b88e9ec6c0f9f905cf9f173e7e947b55e1a18333aec4eff7f23194418099cd, and its expected dimensions are 1672 × 941 pixels.
DOM presence
The homepage contains a real img element with explicit dimensions, eager loading, high fetch priority, and descriptive alternative text. The image is not merely optional CSS decoration.
Viewport evidence
Automated layout checks verify image loading, visible area, navigation behavior, declaration-bar separation, horizontal overflow, first-screen action visibility, and responsive stacking.
Evidence boundary. Local browser rendering verifies the packaged layout under identified viewport conditions. It does not prove a live CDN, browser cache, cPanel, Passenger, or production deployment.
