/* ---------------------------------------------------------------------------
   Panel — design tokens and components.

   Hand-written, no build step. Two rules run through the whole file:

   1. The ACCENT marks the primary action. Semantic colour — amber, blue, green,
      violet, red — means ORDER STATE and nothing else. The accent is never used
      to signal "good", because a customer scanning a list of orders reads
      colour before words.

   2. Dark mode exists from the first line. Retrofitting it after the components
      are written means touching every file, so every colour is a token and the
      dark set is defined immediately below the light one.

   Designed at 390px first. Most orders are placed on a phone, one-handed, by
   someone who has done it a hundred times and wants it to take fifteen seconds.
