/* Pilanda Systems - brand concept CI/CD, draft v0.2 of 2026-10-05.

   One brand colour, and it says something: grey carries the current state
   and the break, petrol the fix and the closed gap. There is no second
   accent - the signal orange and steel blue of v0.1 are gone.

   The contrast rule from section 7.3 is recomputed and holds here: petrol
   #008B8A carries only areas, graphics and large type (3.6:1 on paper -
   enough for graphics, too little for text). Body text, links and button
   labels use deep petrol #006B6A: 5.5:1 on paper, white on it 6.3:1.
   Graphit on Papier is 13.8:1.

   Blechgrau #8A9099 stays a line and the current state, as the concept has
   it - as body text it would be 2.8:1. Secondary text therefore takes a
   darker Graphit tone.

   Light only, on purpose: a sales presence should look the same on every
   machine, even when the operating system is set to dark. */
