/* ============================================================================
   Meridian system theme
   ----------------------------------------------------------------------------
   The system was built on Bootstrap with the default palette, which is why it
   looked identical to APM. This file re-skins it from one place: brand tokens,
   Bootstrap component overrides, and polish for the shared shell.

   It is loaded AFTER each layout's inline <style> so it wins on colour, and it
   touches presentation only -- no layout structure, no behaviour. Every rule
   here changes how something looks, never what it does.

   Brand colours are sampled from the logo: navy #00296c, teal #019196.

 * now drives the section title, the icons, the active pill, and the rail,
 * so you can find a module by colour before reading a word.
 *
 * Hues are spaced around the wheel so no two groups read alike, and tuned for
 * legibility on the graphite sidebar rather than for vividness.
