   styles.css — the ONE stylesheet for the whole site.

   You barely know CSS? Good news: to change how the site LOOKS, you almost
   never touch anything below the ":root" block. Just edit the variables in
   :root (colors, spacing, fonts) and the whole site updates.

   Map of this file:
     1. :root  ........ all design tokens — EDIT HERE to restyle
     2. reset / base .. sensible defaults
     3. layout ........ page width + the top nav + footer
     4. type .......... headings, body, links
     5. components .... contents list, timeline, projects, photos, notes
     6. a11y / motion . focus rings, reduced-motion, gentle load fade
     7. responsive .... phone tweaks
