  Single stylesheet for the whole site. Mobile-first, no dependencies.

  Colour source: assets/img/logo.gif (navy script, lime-green bar, grey bar).
  Contrast ratios checked against WCAG AA (4.5:1 normal text, 3:1 large text/UI):
    --color-navy      (#1f3c88) on white  : 10.2:1
    --color-navy-dark (#14295a) on white  : 14.1:1
    --color-green     (#4d7318) on white  :  5.6:1  (accessible text variant of the logo green)
    --color-grey-900  (#222226) on white  : 15.9:1
    --color-grey-700  (#4b5563) on white  :  7.6:1
    --color-red       (#9f0408) on white  :  8.4:1  (matches the original inline "highlight" red)
    white on --color-navy                 : 10.2:1
    white on --color-green-dark (#3c5813) :  6.9:1
  --color-lime (#8dc63f), the bright logo green, is used only for decoration
  (borders, subtle backgrounds, focus rings) — never as text on white.
