/* Brand palette
   Deep navy #071A2B  | Near-black #05080B | Off-white #F5F7F4 | Acid lime #B7F000 | Muted blue-grey #71808D
   Acid lime is a fill and highlight colour. On off-white it is too light to carry text, so in light mode
   text and links use navy; lime is used for buttons, markers and active states, and as the accent in dark mode.
   A few tints are derived from the palette (panel, line, muted text) to keep text at accessible contrast. */
