/*
  Larder base stylesheet. Hand-written, no component library.
  Served under style-src 'self': never use inline style attributes in .razor
  files; add a class here instead. Phone first (iPhone Safari): safe-area
  insets, 100dvh layouts, 44 px tap targets and 16 px form controls so Safari
  does not zoom. No hover-only affordances: every :hover rule is paired with
  :focus-visible. Every colour is a token in the two blocks below, so the dark
  scheme covers every component by redefining the tokens only.
