/* ==================================================================
   Stoic Science: main stylesheet (shared by every page)

   How this file is organised:
     1. Fonts         - Inter, self-hosted from /fonts (no Google calls)
     2. Design tokens - colours, spacing, widths as CSS variables.
                        Change a colour here and it changes everywhere.
     3. Base          - default look of plain HTML elements
     4. Layout        - the page container
     5. Header & nav
     6. Hero          - navy block with the framed headline
     7. Tagline band
     8. Sections      - white content areas
     9. Buttons
    10. Footer
    11. Accessibility helpers
    12. Inner pages   - compact page header, cards, chips, lists
    13. Blog          - post list and article pages

   Remember: after any change here, bump the ?v= number on the
   <link> tag in every page, so browsers fetch the new version.
