   BulkTranscripts design system — warm bone canvas, hairline grid

   Structure comes from 1px rules dividing content into cells, not from floating
   cards with shadows. Shadows are near-absent by design: on a light canvas they
   read as dirt rather than depth.

   Colour is contrast-led:
     brand  #5b3fd9 — white text 6.65:1, on canvas 6.00:1
     ink    #16181d — 16.03:1 on canvas
     ink-2  #5a5f6b — 5.77:1
   Data series use the palette's LIGHT column (#2a78d6 blue, #eb6834 orange);
   the dark-mode steps were validated against a dark surface and would fail here.
