   CertLogIQ — UI System

   One palette, one radius scale, one type scale. Every colour in the app
   should resolve to a token in this file. If a screen needs a colour that
   isn't here, the answer is almost always that it should reuse one that is.

   DESIGN THESIS
   This is a compliance instrument, not a consumer app. A technician reads it
   one-handed, in a corridor, often in gloves, often in bad light, and the
   thing they need to know in under a second is: is this asset compliant.

   Therefore RED IS A SIGNAL, NOT A DECORATION. Today red is the brand colour,
   the header colour, the button colour AND the fail colour — so it carries no
   information. Here it is reserved for exactly three things: a failed test,
   an overdue compliance date, and the single primary action on a screen.
   Everything else is graphite and paper. Restraint is what reads as "built by
   a developer who knew what they were doing".

   A 3px bar on the leading edge of every asset and job row, colour-coded to

   Why this and not a badge or a coloured card: it is readable in peripheral
   vision while scrolling fast, it costs no horizontal space on a phone, and
   because it's the only place colour appears in a list, a single red spine
   in a screen of green ones is impossible to miss. It's also the one thing
   in the app that will be recognisably ours in a screenshot.  */
