brand-setup

Extract brand identity from a URL. Detect and install fonts in an EDS project via Adobe Fonts or Google Fonts. Extract colors, spacing, favicons.

Script Location

Own scripts:

if [[ -n "${CLAUDE_SKILL_DIR:-}" ]]; then
  BRAND_DIR="${CLAUDE_SKILL_DIR}/scripts"
else
  BRAND_DIR="$(dirname "$(find ~/.claude \
    -path "*/brand-setup/scripts/font-detect.js" \
    -type f 2>/dev/null | head -1)" 2>/dev/null)"
fi

Sibling css-query.js (from migrate-header):

if [[ -n "${CLAUDE_SKILL_DIR:-}" ]]; then
  CSS_QUERY="$(dirname "$CLAUDE_SKILL_DIR")/migrate-header/scripts/css-query.js"
else
  CSS_QUERY="$(find ~/.claude \
    -path "*/migrate-header/scripts/css-query.js" \
    -type f 2>/dev/null | head -1)"
fi

Verify both paths exist before proceeding.

Arguments

| Argument | Purpose | |----------|---------| | <url> | Target URL (required) | | --kit=<kitId> | Typekit kit ID (default: detected from page, or cwm0xxe) | | --no-configure | Extract only — skip EDS project configuration | | --only=fonts | Detect and install fonts only, skip colors/spacing/favicons | | --browser-recipe=<path> | Pass to css-query.js for bot-protected sites | | --output=<path> | Output path for brand.json (default: ./brand.json) | | --session=<name> | Playwright session name (default: brand-setup) | | --dry-run | Preview font resolution without mutations |

Environment

| Variable | Purpose | |----------|---------| | ADOBE_FONTS_API_TOKEN | Typekit API token for adding fonts to kits. Get from fonts.adobe.com/account/tokens. Without this, fonts found in Adobe Fonts cannot be auto-added — falls through to Google Fonts. |

Workflow

Set SESSION from --session (default: brand-setup), OUTPUT from --output (default: ./brand.json).

Step 1 — Open browser session

node "$CSS_QUERY" open "$URL" --session="$SESSION"

If --browser-recipe was provided, add the flag. If the open fails, suggest running browser-probe first to detect CDN bot protection.

Step 2 — Detect fonts

Run the 4-layer font detection IIFE. This awaits document.fonts.ready internally, so no separate wait step is needed.

node "$BRAND_DIR/font-detect.js" --session="$SESSION" \
  --output=fonts-detected.json

Output: fonts-detected.json with body/heading fonts (by computed style voting across all p/h1-h3 elements), loaded font families from document.fonts, and source detection (Typekit kit ID via CSS import rules, Google Fonts URLs, Performance API resource entries).

Step 3 — Install fonts

Resolve detected fonts through the 5-step cascade and update head.html:

node "$BRAND_DIR/font-install.js" \
  --detected=fonts-detected.json \
  --kit="$KIT_ID" \
  --head-html=head.html

The --kit value comes from (in order of precedence):

1. User-provided --kit argument
2. Kit ID detected from the source page (fonts-detected.json → sources.typekit.kitId)
3. Default fallback kit cwm0xxe

If ADOBE_FONTS_API_TOKEN is set, fonts found in Adobe Fonts are automatically added to the kit and published. Without the token, only fonts already in the kit are used; others fall through to Google Fonts.

Add --dry-run to preview resolution without making changes.

If --only=fonts was passed, skip to Step 6 (close session) after this step.

Step 4 — Extract brand visuals

Run the DOM extraction for colors, spacing, heading sizes, and favicons:

node "$BRAND_DIR/brand-extract-dom.js" --session="$SESSION"

Output includes:

• colors: background, text, link, linkHover
• spacing: sectionPadding, contentMaxWidth, navHeight
• headingSizes: h1→xxl through h6→xs with desktop font-size
• favicons: all icon links with URLs, sizes, types

Step 5 — Build brand.json

Merge font detection + installation results with visual extraction:

{
  "url": "<source URL>",
  "fonts": {
    "body": { "family": "...", "stack": "...", "delivery": "typekit" },
    "heading": { "family": "...", "stack": "...", "delivery": "same-as-body" },
    "headingSizes": { "xxl": { "desktop": "44px" } },
    "sources": { "typekit": { "kitId": "...", "method": "css-import" } }
  },
  "colors": { "background": "...", "text": "...", "link": "...", "linkHover": "..." },
  "spacing": { "sectionPadding": "...", "contentMaxWidth": "...", "navHeight": "..." },
  "favicons": [{ "url": "...", "rel": "icon" }]
}

Write to $OUTPUT.

Step 6 — Close session

node "$CSS_QUERY" close --session="$SESSION"

Always close, even if earlier steps fail.

Step 7 — EDS configuration (optional)

Skip if --no-configure was passed.

Detect EDS project by checking for fstab.yaml, scripts/aem.js, or head.html in cwd. If none found, skip and report brand.json only.

Note: head.html font links were already added in Step 3 by font-install.js. This step handles the remaining configuration.

7a. Download favicons

curl -sL "<favicon-url>" -o "<filename>"

7b. Create styles/brand.css

:root {
  --heading-font-family: "<heading stack>";
  --body-font-family: "<body stack>";
  --background-color: <background>;
  --text-color: <text>;
  --link-color: <link>;
  --link-hover-color: <linkHover>;
  --content-max-width: <contentMaxWidth>;
  --section-padding: <sectionPadding>;
  --nav-height: <navHeight>;
}

Only include properties with values.

7c. Update styles/styles.css

Add @import url('brand.css'); as the very first line. Idempotent — check before adding.

Step 8 — Report

Brand extracted from <url>
  Body font: <family> (<resolution>)
  Heading font: <family> (<resolution>)
  Typekit kit: <kitId> (published: yes/no)
  Colors: bg=<bg> text=<text> link=<link>
  Favicons: <count>
  Output: <brand.json path>

Error Handling

• If css-query.js open fails → suggest browser-probe for recipe
• If font-detect.js returns empty fonts → warn, continue with visuals
• If font-install.js can't add to kit (no token) → warn, try Google Fonts
• If Google Fonts check fails → warn, font declared in CSS but not delivered
• Always close session in Step 6, even on failure
