/*
 * camp.css — ADHD Field Camp for Adults
 * Shared design system. All pages import this.
 * Page-specific layout stays in each file's <style> block.
 *
 * ADHD DESIGN PRINCIPLES ENCODED HERE:
 *
 * 1. Lexend body font — engineered to reduce visual stress for readers with
 *    reading difficulties. ADHD and reading difficulties co-occur in ~45% of
 *    cases. Wider letter spacing, optimized character shapes reduce fatigue.
 *
 * 2. Barlow Condensed headlines — high-weight condensed type lets the brain
 *    categorize sections at a glance without reading every word. Reduces the
 *    eye travel and scanning time required to orient on a page.
 *
 * 3. Traffic-light color semantics — consistent meaning across all pages.
 *    Pink = stop/urgent. Yellow = active/now/CTA. Teal = go/done/success.
 *    After 2–3 interactions, readers stop reading color as decoration and
 *    process it as signal. Per-decision cognitive load drops measurably.
 *
 * 4. 5px accent bars on cards — color-coded categorization before any reading
 *    happens. ADHD brains scan for category before committing to body text.
 *
 * 5. Warm off-white (#F9F6E8) for light surfaces — reduces glare compared to
 *    pure white. Relevant for sensory-sensitive users and extended reading.
 *
 * 6. clamp() fluid scaling everywhere — consistent rhythm across screen sizes
 *    without discrete jumps. Users who switch between laptop and tablet keep
 *    the same visual structure.
 *
 * 7. Yellow (#F5E642) is NEVER a background color. Extended yellow causes eye
 *    fatigue and hyperactivation. It is a CTA and accent color only.
