/*
  Admin panel styles.

  A tool used all day: dense enough to see many rows at once, but calm enough to read for hours.
  Light theme only, deliberately - the previous version followed prefers-color-scheme and flipped
  to dark on most machines, which made the panel look inconsistent from one desk to the next.

  The palette is a single blue accent against warm greys. Colour is reserved for meaning (status,
  destructive actions), never decoration, so a red badge always means something is wrong.
