/*
  Khwarizmiat — v1.1 (English, LTR)

  Logical properties are used throughout (margin-inline, padding-block,
  border-inline-start, text-align: start, etc.) instead of left/right
  equivalents so a future Arabic/RTL version is a CSS + content swap,
  not a rebuild. CSS Grid column tracks already follow the inline axis
  of `direction`, so no extra logical handling is needed there.

  Color is functional: Signal Magenta = action/feminist emphasis, Circuit
  Blue = systems/technical content, Manuscript Gold = heritage reference.
  All three now carry full-fill backgrounds (tags, buttons, hover states)
  as well as line art — text color pairings below were chosen by checking
  contrast against the *current* token values (see README for the numbers);
  changing a token requires re-checking these pairings, not just swapping
  the hex value.
