Logo surface board

The generator's 2K preview flatters every candidate; small-size and reversed rendering is what kills marks.

Procedure

1. Generate 3 candidates with identical params from a vector-capable image model (e.g. Recraft V4.1 with --model_type vector, --colors @colors.json, --background_color, 1:1, 2k). Run them in parallel (e.g. a ThreadPoolExecutor calling the generator CLI). If you generate through Higgsfield, call the Skill tool with "higgsfield-generate". If "higgsfield-generate" isn't installed, ask the user to run npx skills add higgsfield-ai/skills --skill higgsfield-generate, then continue.
2. Audit each SVG deterministically: re.findall(r'fill="(rgb\([^)]*\))"'). If the mark fill is not the locked hex, repair the fill token only (re.sub on non-background fills). Never regenerate for a colour miss; regenerate only for geometry.
3. Rasterize 32px and 120px with rsvg-convert; build a strip with magick ... ( 32px -filter point -resize 400% ) +append and LOOK at it. Marks that turn into UI icons (link chain, cog, viewfinder, bucket) at 32px are dead regardless of the 2K render.
4. Crop each mark to a transparent square viewBox: drop <metadata> and the first background-filled path, rasterize, magick -trim -format '%w %h %X %Y', pad 8%, rewrite viewBox, remove width/height, set preserveAspectRatio="xMidYMid meet".
5. Write one throwaway index.html with an <article data-mark> per candidate: primary, reversed (CSS .rev .mark path{fill:bg}), app tile, 16/24/32/48 favicons, nav lockup with the wordmark (plus the second-script wordmark, e.g. Arabic, when the brand uses one), and mock home + product-detail pages in the brand palette. A fixed bottom bar switches via ?mark= search param.
6. Serve with python3 -m http.server <port> --directory <dir> as a background process. Open it in a dedicated browser tab and keep that tab's id; target that tab on every later browser command so another agent session sharing the worktree is not disturbed. Verify with an evaluate in the page: shown article, svg count, none zero-size, no overflowX, bar text. Then screenshot that tab.
   • With Orca's browser: orca tab create --url ... --json returns a browserPageId; pass --page <id> on every later orca eval and orca screenshot. If "orca-cli" isn't installed, ask the user to run npx skills add stablyai/orca --skill orca-cli, then continue.
7. Commit the board to prototype/<name> from a temp worktree, push, remove the worktree, and post a table (mark, mechanism, 32px verdict, SVG links, branch link) on the ticket. Stop for the human's pick; never self-approve.
