/* ---------------------------------------------------------------------------
   Knowledge vaults — book form and assistant editor.

   Theme-aware throughout: every colour is a variable from css/themes/, so this
   reads correctly on all themes. No hardcoded #fff, and semi-transparent
   surfaces use color-mix against a token rather than rgba().

   No emojis: status and type are carried by inline SVG and CSS shapes, both of
   which take currentColor and so follow the theme.

   Emphasis comes from a tinted icon plate and a soft corner wash, never a thick
   coloured border down the edge of a container.
