   Petrion Labs — design system
   ----------------------------------------------------------------------------
   Source of truth: "Petrion Labs — Master Colour Palette".
   Slate is the brand. Amber is the verb.

   THE AMBER BUDGET IS A HARD RULE, NOT A SUGGESTION:
     · One amber element per screen. A second one breaks the first.
     · Amber is always a FILL with dark text on it — never coloured text
       on a light ground. Need amber text? --action-text handles it.
     · No amber warning states. Warning is burnt orange (--warning).
     · No second accent. Ever.
     · Every grey comes from the slate ramp. No #888, no pure #000.

   Semantic tokens follow the shadcn/ui naming convention so the classes here
   map 1:1 onto a future React + shadcn build with no re-theming.
