   4D-Bio — Association of Bioinformatics Professionals house style
   ---------------------------------------------------------------------------
   Applies the BioinfoPro design system to MkDocs Material.

   Non-negotiables carried over from the design system:
     - Five brand colours only (+ listed tints for text hierarchy / quiet fills)
     - No shadows, gradients, photography, patterns, textures, illustration
     - One radius (0.5rem; pill for tags), one border (1px alice blue),
       one transition (0.15s ease)
     - Sentence case everywhere except the uppercase eyebrow label
     - Space Grotesk for display, Inter for everything else
     - Light only — the brand defines no dark mode
   Docs-platform deviations are noted inline.
