The primary action is signature material, not chrome

The Tortuga comp dissolves the Install CTA's edge into the storm's
particles; the build shipped a plain rectangle with four decorative
dots, and neither the builder nor the reviewer's rebuild findings named
it. The inventory now gives the primary action its own row and medium,
naming the shrink-to-border-trick failure as the compliance-token
version of commitment, and the reviewer's fidelity matrix lists the
primary action's treatment among the salient elements, with a
physically-worked CTA rendered as a plain rectangle scored contradicted.

 ## Inventory implementation fidelity
 
-Before building, inventory the approved comp's major visible ingredients in writing (a short table in the surface brief or working notes; the finish reviewer audits shipped assets against it) and choose an implementation medium for each: semantic HTML/CSS/SVG, existing project asset, generated raster, sourced raster, icon library, canvas/WebGL, or accepted omission. The same written inventory names the comp's compositional commitments: navigation items and icons, headline levels and their scale relationship, signature geometry such as seams, masks, and overlaps, and each section's arrangement and density. An element never written down is the element the build silently drops, and the direction contract's 150 words cannot carry this list, so this inventory is where it lives.

The primary action gets its own row with its own medium: when the comp dissolves, stamps, erodes, or otherwise physically works the main CTA, that treatment is signature material on the page's most important element, and shrinking it to a border trick or a few decorative pixels is the compliance-token version of commitment. An element never written down is the element the build silently drops, and the direction contract's 150 words cannot carry this list, so this inventory is where it lives.
 
 The medium column is where an approved design most often dies, so it obeys a gate: the medium is decided by what the comp region shows, never by what feels buildable in the current stack. A human figure, a product object, machinery, or any material with lighting and depth is raster whatever the stack; writing "silhouette" for a photographic figure, or "CSS" for a sculpted panel's finish, is not a medium choice, it is the quiet deletion of the approved design, and it is how a comp full of physical material becomes a flat page with the same section order. Style does not move this boundary: a comp region with perspective, shading, figure drawing, or dense mechanical detail is illustration however line-drawn it looks, and no build session can author illustration as vectors, so it regenerates as raster like any photograph. Authored SVG covers what a session can specify exactly, diagrams with countable elements, controls, flat shape systems, and it ends where drawing skill begins; an instruction-manual world does not convert its illustrations into diagrams, it makes them line-art illustrations. Produce such regions by regenerating them cleanly, with the approved comp and its embedded prompt as the reference for a fresh render at asset resolution; never crop pixels out of the comp itself, whose effective resolution sits far below asset grade. Dropping an image-native region instead of producing it is a scope decision the user makes at the approval point, never a silent flattening after it. Generated imagery is a material, not a claim: evidence rules bind assertions, specs, testimonials, and photographs presented as real, never render fidelity, so "no photography on hand" forbids fake proof, not an illustrated hero.
