/* Compass Vault design system. One file, no dependencies, no external fonts or images.
   The Portal (wwwroot/css/compass.css) and the Gateway (wwwroot/assets/compass.css) ship IDENTICAL copies; a test enforces it.
   Dark is the default. Light applies when the visitor's system prefers it, or when data-theme="light" is set. data-theme="dark" forces dark.

   Colour roles:  indigo/blue = structure and navigation,  teal = actions and success only,  red/amber = danger/warning.
   Scales:        space 4 8 12 16 24 32 48 64 (--s1..--s8) · radius 8 12 18 (--r1..--r3) · type 12 14 16 18 22 30 40 (--t0..--t6). */
