/* ===============================================================
   Shared Project Page Styles — V5 aligned
   Used by: projects/project1.html, project2-science.html,
            project2-systems.html, projects.html

   Load order on every project page:
     1. core-styles.css    (base + pre/code + .callout)
     2. v5-tokens.css      (design tokens — --v5-* + --m1..m6)
     3. v5-projects.css    (v5 chrome: nav, h1/h2, body bg)
     4. project-styles.css (this file — page components)

   Design language: V5 minimal.
   - Surfaces: white cards on a pale neutral page background.
   - Borders: 1px hairlines, no heavy color frames.
   - Accent: a single blue (m1) left-bar on key surfaces — sparingly.
   - Headings: Fraunces serif (inherited from v5-projects).
   - Body: Inter Tight sans.
   - Code: dark theme inherited from core-styles.css (pre::before
     labels replaced per-language below).
