/* public/css/styles.css
   Plain CSS, no build tools — every page loads this one file (linked in
   views/partials/head.ejs). It's organized top to bottom as:
     1. CSS variables (colors, spacing) — change these to re-theme the whole site
     2. Reset / base styles
     3. Layout helpers (container, sections)
     4. Reusable components (buttons, cards, pills, timeline)
     5. Page-specific bits (hero, header, footer)
