/* ==================================================== tool-page.css — ClickShot · Shared component library for all tool / service pages (parsers, analyzers, converters, API explorers, dashboards). Depends on: base.css (design tokens, fonts, ink scale) ==================================================== PHILOSOPHY ────────── Tool pages share one visual language that sits distinct from the marketing landing: same design system tokens from base.css, but tighter density (13 px base font), a white background (no bone), and lime (#C5FF1A) as the sole accent for interactive states. Audience is specialists who need information density, not visual theater. CREATING A NEW TOOL PAGE ──────────────────────── See the clickshot-tool-page skill (.claude/skills/) for the full step-by-step guide, copy rules and conventions. Quick version: 1. Copy landing-php/tool/firecrawl/ as your starting template. Tool pages live in tool// (two levels below css/). 2. Add class="fc-app" to . 3. Link in (in this order): 4. require_once sections/icons.php; include sections/nav.php. 5. Build with the components below; see HTML SKELETON. 6. Write JS in tool//script.js. 7. Add the help-modal JS snippet (see HELP MODAL section). Icons: use icon('name', size) from sections/icons.php — never emoji (brand rule). The skeleton below uses icon() calls for that reason.
