/* ==========================================================================
   WD Power brand tokens.

   Measured off the master logo (QMS/Images/WDpower-logo-Small-01.jpg), not
   guessed: the flat fill areas are #404B9B and #FFF100. Everything below is
   derived from those two.

   Contrast, measured against the surfaces they are actually used on:

     navy   on white          7.78:1   AA  — body links, buttons, headings
     white  on navy           7.78:1   AA  — sidebar text
     yellow on navy           6.61:1   AA  — the signature pairing
     ink    on yellow        16.72:1   AA  — anything sitting inside a yellow chip
     yellow on white          1.18:1   FAIL

   That last line is the rule that shapes the whole system: brand yellow can
   never be text, a hairline, or an icon on a light surface. It is a block
   colour that carries ink, or an accent sitting on navy. Nothing else.

   THESE ARE CHROME COLOURS AND NEVER ENTER A CHART.
   The categorical --viz-* ramp below is validated for CVD separation, and the
   brand pair lands on top of two of its slots — navy is dE 20.4 from --viz-7
   violet and dE 21.0 from --viz-1 blue, brand yellow is dE 37.2 from
   --viz-warning. Painting a series brand-navy would put two near-identical
   blues in one legend; painting anything brand-yellow next to a warning pip
   makes an accent look like a status. Frame, nav, buttons and headings are
   brand. Data marks and status are --viz-*. The two vocabularies do not mix.

   Data-visualisation tokens.

   Roles, not raw hex, so light and dark swap in one place. The categorical
   order is fixed and validated — slots are assigned by entity, never by rank,
   so filtering a series out never repaints the survivors.

   Validated with the dataviz palette validator:
     light  worst adjacent CVD dE 9.1, normal-vision dE 19.6  (three slots are
            below 3:1 on the light surface, so every chart ships direct labels
            and a table view — that is the required relief, not an option)
     dark   worst adjacent CVD dE 8.4, normal-vision dE 19.3, all >= 3:1
