   Portfolio Dashboard — shared stylesheet for the landing site.

   Every page under website/ links this file. It used to be four near-identical
   copies of the same inline <style> block, which is how privacy.html quietly
   drifted onto a different palette. One file, one set of tokens.

   Colours are chosen to clear WCAG AA (4.5:1) for body text on every surface
   they are used against. If you add a colour, check the ratio before shipping.
