Goal: Store Icon Progress Overlay

Use Krypton Execution to execute docs/goals/store-icon-progress/PLAN.md after the required Buy-store fixture and catalog icon URL evidence are available.

Core rules:

• Treat PLAN.md as the source plan.
• Create data/fixtures.json from the reviewed 17-file corpus before changing recognition behavior.
• Keep fixture expected data human-owned; tests may report actual values but must never bless or rewrite expectations automatically.
• Keep fixture calibration, templates, catalog JSON/icon bytes and sequence pending/found states human-owned and versioned.
• Run fixtures through the single src/frame-analyzer.js#analyzeFrame path used by live capture; remove the inline implementation from main.js and do not create a test-only parser.
• Use real production OpenCV/Tesseract/parser in the Playwright lane; substitute only catalog transport with committed fixture assets.
• Preserve the active result as slot-state truth owner.
• Keep old six-field calibration readable and operational.
• Do not infer the parsed slot from tooltip position or hover order.
• Mark a slot green only for a unique best visual match above both the absolute threshold and second-best margin; ties remain yellow.
• Do not send runtime images or slot state to the backend.
• Make the active source preview readable at the real source-card scale before accepting overlay evidence.
• Verify optional grid calibration survives the hosted PUT-to-GET round trip.
• Capture yellow-to-green browser evidence and record it in EVIDENCE.md.
• Finish with one npm run check gate covering unit tests, all fixture screenshots, the production build and git diff --check.
• Say implemented but unproven if Buy/Sell or catalog-icon matching cannot be demonstrated.
