/* ---- Link floor ----
   Every link colour in this sheet is scoped to a component (.seealso a, and
   friends). Nothing sets a colour on a bare `a`, so a link that no component
   happens to name falls through to the browser's own stylesheet: #0000EE, and
   #551A8B once it has been clicked. Nothing in the shipped markup lands there
   today — but this app writes anchors from JS, and the identical gap on the
   main site was rendering browser-blue links on 59 of its pages, the visited
   ones flipping hue hard enough to lose your place in a list.

   A floor, not a component style: at 0-0-1 it is the weakest selector that can
   exist, so every rule below still wins. `color` only — adding text-decoration
   here would reach past the fall-through links into components that leave
   decoration to the UA sheet. And an author `color` on `a` is itself what
   disables the UA :visited purple, so there is no :visited rule to write. Do
   not add a blanket `a:visited`: at 0-1-1 it would outrank the component rules
   and repaint links the moment a reader clicked them.

   .cta and .headline are the dark surfaces; the light floor measures 2.25:1 on
   #152D49, so unclaimed links there take white (13.97:1) instead. :not([class])
   keeps both floors off any link a component has already claimed.

   This block is byte-identical in all six tools — keep it that way. */
