09 — Brand and Content System

Extract real brand assets and apply the full copy system (anti-slop, SEO, trust surfaces, GEO) to every website build surface.

Model migration note (pass-77, 2026-06-09): DALL-E → GPT Image 2 (2026-04; 2.5 branded 2026-09 — check current API id at integration) + GPT-4o → GPT Image 2 vision. Per platform.openai.com/docs/deprecations. Brand extraction protocol unchanged.

Brand Extraction (Rebuilds)

1. Screenshot existing (Wayback if down); extract logo/colors/fonts/tone. Never discard equity.

2. Color extraction (NON-NEGOTIABLE) — Screenshot with Playwright, GPT Image 2 vision extracts hex (logo priority), cross-ref logo, build palette, validate WCAG AA. NEVER invent, NEVER use Emdash defaults for clients, NEVER infer from category.

3. Second-pass verification (BUILD-BREAKING — pre-deploy) — After GPT Image 2 vision returns {primary, secondary, accent}:

   • Load logo PNG via sharp, sample dominant chroma via k-means k=5 ignoring transparent + near-white/near-black (top-3 cluster centroids in HSL)
   • For EACH color, compute min HSL hue-distance to top-3 logo chromas — if min_hue_distance > 30° AND saturation>0.2, FAIL w/ diagnostic
   • Re-run GPT Image 2 vision w/ corrective prompt naming top-3 logo chromas + demanding primary derived from one
   • Validator: validate-color-from-logo.mjs in build_validators.ts between brand-research and template-pick
   • NEVER ship primary color failing hue-distance check

4. Logo-luminance + source-theme drives theme (NON-NEGOTIABLE) — Two-signal:

   • Signal A: logo dominant-color luminance (WCAG formula)
   • Signal B: source-site dominant background luminance (Playwright screenshot of body background)
   • BOTH agree → match; disagree → source-site wins UNLESS source design score <7/10 (then logo wins)
   • High-quality source (≥7/10 via GPT Image 2 vision detail:low) → match source theme verbatim
   • Set theme BEFORE template selection. Reject palette where logo-on-bg contrast <4.5:1 (WCAG AA).
   • "Dark-first" applies to accent-rich Emdash/SaaS brands, NOT to logo-driven non-profit/serif clients or high-quality light-themed source brands

5. Logo-vs-container contrast (BUILD-BREAKING — every render) — Every logo render (header, footer, hero, modal, splash, mobile menu, sidebar) MUST contrast container bg by ≥4.5:1 on logo's dominant chroma (not transparent pixels)

   • Forbidden: white-text-logo on white/cream | dark-text-logo on dark/navy | low-saturation-logo on same-hue bg
   • Resolution: header AND footer themes chosen AFTER logo luminance scan. Dual-theme site needing SAME logo → ship TWO files (brand-mark-light.svg for dark bg, brand-mark-dark.svg for light bg) + CSS <picture><source media> swaps
   • Automate via skill 12 logo-variant-generator (Real-ESRGAN inversion or magick -channel RGB -negate; color logos w/ text → GPT Image 2 w/ "same logo on transparent bg w/ text inverted to <opposite-luminance>")
   • Validator: validate-logo-contrast.mjs — Claude Sonnet 4.6 vision samples logo bbox + container computed bg at 6bp + pixel sampling, fails if <4.5:1

6. Brand-element extraction (logo is gold mine — extract DNA) — GPT Image 2 vision returns {font_family_guess, suggested_heading_font, suggested_body_font, font_weight, letterspacing, has_icon_mark, icon_mark_description, icon_mark_dominant_color, decorative_motif_description, motif_extractable (bool)}

   • Matched Google Font → --font-heading site-wide
   • motif_extractable=true → crop icon-only region (magick logo.png -alpha extract -trim +repage), upscale 2-4× via Real-ESRGAN / GPT Image 2 variation, save as assets/brand-splash.png + assets/brand-mark.png

7. Logo singularity (BUILD-BREAKING — exactly ONE logo file per container) — Every logo container renders EXACTLY ONE logo asset

   • Never composite two logo sources side-by-side; never stack icon-mark + wordmark as separate <img> tags; never render apple-touch-icon.png next to logo.svg in same container
   • Composition at asset-prep time via magick logo-mark.png logo-wordmark.png +append, NOT at render time
   • Validator: validate-logo-singularity.mjs parses dist/ HTML; count>1 descendant <img> or inline <svg> in same logo container = FAIL

8. Logo (NON-NEGOTIABLE) — Every project needs premium logo. See Skill 12 for full process.

9. Audit — logo found + rated ≥7/10 + works 16-512px, colors EXTRACTED, palette WCAG AA, typography + tone + messages identified.

Brand Extraction from Physical Assets (LOCAL BUSINESS — NO WEBSITE)

• Street View Static API: https://maps.googleapis.com/maps/api/streetview?size=1200x800&location={lat},{lng}&source=outdoor
• Places photos: filter types: ["exterior", "storefront"]
• GPT Image 2 vision on storefront — prompt: "Extract brand identity from this business storefront photo. Return JSON: {sign_text, sign_font_style, primary_color (hex), secondary_color (hex), accent_color (hex), logo_description, overall_aesthetic, confidence (0-1)}"
• Business cards: GPT Image 2 vision extracts logo (crop region), colors (exact hex), font, tagline, NAP for verification.
• Color extraction priority: 1. Signage → 2. Logo → 3. Storefront awning/trim → 4. Interior decor → 5. Vehicle wrap → 6. Business card → 7. Category default (LAST RESORT). Each tagged with color_source.
• Font matching from signage: Script → Dancing Script | Serif → Playfair Display | Modern sans → Inter | Hand-lettered → Caveat. Never use exact proprietary fonts.

Brand Inference (New Products)

• Dev tool → technical/dark/monospace | SaaS → professional/clean/cards | Agency → confident/bold
• E-commerce → friendly/product-focused | Nonprofit → warm/impact imagery | API → technical/docs-forward
• Emdash defaults (NOT for clients): #00E5FF, #50AAE3, #060610. Sora / Space Grotesk / JetBrains Mono.

Anti-AI-Slop Detection (MANDATORY SCAN)

Banned copy words: delve | leverage | unleash | revolutionize | best-in-class | cutting-edge | discover | innovative | seamless | robust | synergy | elevate | empower | transformative

Banned patterns: "Welcome to" | "Discover [product]" | vague aspirational headlines | hedging ("may help you," "can potentially") | generic superlatives

Banned design tells: Inter as sole font | purple-blue gradients | uniform 16px border-radius everywhere | centered everything | Hero/Lucide as sole icon set | abstract 3D blobs | uniform fade-in on all elements | plastic AI stock photos

Fix: ask "Would the founder actually say this?" No → rewrite.

Copy System

• Headlines — benefit-first, specific, numbers, max 8 words
• Subheadings — expand promise, 15-25 words
• Body — one idea/paragraph, 2-4 sentences, active, concrete, benefit-oriented
• CTAs — specific action verb first, gradient primary + ghost secondary, above fold + page end
• Never: "Click here" | "Submit" | "Learn more"
• Personality mapping — Expert → precise industry terms | Direct → short declarative | Pragmatic → outcomes/implementation
• Vocabulary: always-use / never-use / prefer-over lists | max sentence: 25 words
• Banned structures: passive voice, hedging, em dashes mid-sentence | monthly drift audit

Microcopy System

• Error messages — [What happened] + [What to do]. Empathetic, solution-oriented. "Payment failed. Try a different card or contact support." Never "Error 500" or jargon. Flesch 70+.
• CTAs — action verb first, max 3 words preferred: "Start building" | "Ship today" | "Get access"
• Empty states — acknowledge absence + suggest action: "No projects yet. Create your first one." Never just "No results"
• Toasts — past tense success ("Project created"), present in-progress ("Saving…"), plain-language errors
• Form labels — noun phrases, sentence case. Helper text: one line, 10 words max

Machine-Readable Brand Documentation

• DESIGN.md (6 sections): 1. Visual Theme | 2. Color Palette (hex + role) | 3. Typography (family + scale + weight) | 4. Spacing + Layout | 5. Components (states + variants + props) | 6. Elevation + Shadows
• Tokens: W3C DTCG JSON format, single source of truth. Generated from tokens.json → CSS vars + Tailwind config.
