/*
  Astryx-pattern styles for the Classico Platforms Brief newsletter.

  Astryx (Meta's design system) ships two things useful to a static, buildless
  HTML page: reset.css (browser reset) and theme.css (the actual token values,
  scoped to [data-astryx-theme="neutral"]). Its component library (astryx.css)
  is StyleX-compiled atomic CSS wired to React component internals — it has no
  meaning without the React components themselves, so this file does not use it.

  Instead: hand-written classes that reproduce Astryx's documented component
  patterns (Card, Badge, Banner, Table, StatusDot) using the real tokens, so a
  reader sees Astryx's actual visual language. All spacing/inset properties are
  logical (inline-start/end) — required for correct Arabic RTL mirroring.

  Load order on every page: astryx-reset.css → astryx-theme.css → this file.
