337## Extraction
338
339- Source: design-md-generator
340- Pages crawled: ${report?.pagesCrawled || rawTokens?.meta?.totalPages || 0}
341- Total elements: ${report?.totalElements || rawTokens?.meta?.totalElements || 0}
342- Screenshots captured: ${report?.screenshotCount || 0}
343${boundary ? `- Design boundary: ${boundary.relationship} (${boundary.overallSimilarity}% similarity)` : "- Design boundary: not reported"}
344
345## Brand Summary
346
347- Site title: ${sourceHost}
348- Visual position: derive from extracted screenshots, token frequencies, component primitives, and copied page evidence.
349- Primary goal: preserve recognizable source brand while rebuilding against evidence-first extraction output.
350
351## Color Tokens
352
353${colors.length ? colors.map((token) => `- \`${token.hex}\` (${token.stability?.layer || "unknown"}, frequency ${token.frequency || 0})`).join("\n") : "- No colors extracted."}
354
355Recommended Tailwind variables:
356
357${[
358 mapColorRecommendations(unique(colors.map((token) => token.hex)).slice(0, 8)),
359 mapFontRecommendations(unique(typography.map((level) => level.fontFamily)).slice(0, 2)),
360 ].map((item) => `- ${item}`).join("\n")}
361
362## Typography
363
364${typography.length ? typography.map((level) => `- \`${level.fontFamily}\` ${level.fontSize} / ${level.fontWeight} / ${level.lineHeight}${level.textTransform ? ` / ${level.textTransform}` : ""}`).join("\n") : "- No typography levels extracted."}
365
366## Layout And Spacing
367
368- Base unit: ${rawTokens.spacingSystem?.baseUnit ?? "unknown"}
369${spacingScale.length ? `- Spacing scale: ${spacingScale.map((value) => `\`${value}px\``).join(", ")}.` : "- Spacing scale: not extracted."}
370${breakpoints.length ? `- Breakpoints: ${breakpoints.map((item) => `\`${item.value}\``).join(", ")}.` : "- Breakpoints: not extracted."}
371- Max content width: ${rawTokens.layoutPatterns?.maxContentWidth || "unknown"}
372- Content alignment: ${rawTokens.layoutPatterns?.contentAlignment || "unknown"}
373
374## Header And Navigation
375
376- Use screenshot evidence from the extracted run for shared chrome.
377- Preserve source direction and navigation order from extracted page evidence before implementing shared header/footer.
378- If the source includes multiple header states, validate them manually from the captured screenshots before simplifying.
379
380## Radii, Borders, Shadows
381
382Radii:
383
384${(rawTokens.radiusTokens || []).length ? rawTokens.radiusTokens.slice(0, 8).map((token) => `- \`${token.value}\` (${token.stability?.layer || "unknown"})`).join("\n") : "- No radii extracted."}
385
386Shadows:
387
388${(rawTokens.shadowTokens || []).length ? rawTokens.shadowTokens.slice(0, 8).map((token) => `- \`${token.value}\` (${token.stability?.layer || "unknown"})`).join("\n") : "- No shadows extracted."}
389
390## Global CSS Recommendations
391
392- Load extracted font families before building page sections.
393- Map high-frequency infrastructure and system colors into theme variables first.
394- Prefer infrastructure and system layers over campaign or content-only tokens.
395- Use screenshot evidence to validate any token that appears only on a small subset of pages.
396
397## Component Patterns
398
399${components.length ? components.slice(0, 8).map((component) => {
400 const variants = (component.variants || []).slice(0, 3).map((variant) => ` - ${variant.name}: ${variant.style?.fontSize || "?"} / ${variant.style?.fontWeight || "?"} / ${variant.style?.backgroundColor || "?"} / ${variant.style?.color || "?"}`).join("\n");
401 return `- ${component.type}\n${variants}`;
402 }).join("\n") : "- No component primitives extracted."}
403
404## Accessibility And Motion Notes
405
406- Primary timing function: ${motion.primaryTimingFunction || "unknown"}
407${(motion.durationScale || []).length ? `- Duration scale: ${(motion.durationScale || []).map((item) => `\`${item.value}\``).join(", ")}.` : "- Duration scale: not extracted."}
408- Reduced motion support: ${motion.prefersReducedMotion === true ? "reported" : "not reported"}
409- Icon system: ${iconSystem.library || "custom or not detected"}, ${iconSystem.totalCount || 0} extracted icon instances
410
411## Implementation Checklist
412
413- Set Tailwind/theme variables before building pages.
414- Add global CSS and font loading from extracted families.
415- Use extracted screenshots to validate header, navigation, hero composition, and footer structure.
416- Build shared header, footer, layout, and CTA components first.
417- Run visual QA against the extracted screenshots after implementation.
