   Brand colours come from the approved final SVG logo fills:
     navy #0B2A4A, logo blue #1688D5, white #FFFFFF.
   Neutrals are supporting UI colours, not brand colours.
   Measured contrast (WCAG 2.x):
     navy on white 14.5:1 · text #172B3A on white 14.6:1 · secondary #526474 on white 6.1:1
     white on logo blue 3.8:1  -> NOT used for normal-size text
     link #0F6DAD on white 5.5:1 · field border #7D8D9C on white 3.4:1 (non-text >= 3:1)
