/* The design system as a component kit (blueprint/spec/design.md,
   "Web"), and the shell the signed-in pages sit in (blueprint/spec/web.md,
   "The signed-in pages"). Every block is BEM and prefixed `filt-`:
   block, then __element, then --modifier, one class per rule, so a
   rule's scope is readable from its name and specificity stays flat.

   Colours, faces, sizes and radii come from tokens.css, linked before
   this file; nothing here names a value of its own except ink on a
   fill, which does not flip with the scheme. Hover is a straight
   colour swap, to the hue's dark value or from secondary ink to ink;
   nothing lifts, scales or glows. Focus darkens the hairline to
   secondary ink. Disabled is opacity .4. */
