/*
  CAREER PACKAGES — SHARED BLADE COMPONENT STYLES
  Batch 36 — Section 54 (Design System).

  Loaded after theme.css. Consumes ONLY the semantic tokens defined
  there (--color-brand, --text-primary, --bg-dark, etc.), never the
  raw color scales directly, per Section 66's "Implementation" note —
  so the palette can move later without touching this file.

  This is one hand-written stylesheet, not a build pipeline (no
  Sass/PostCSS/Vite step exists in this sandbox — see the project
  README's standing note that nothing here has been run against a
  real install). It is organized top-to-bottom to match Section 54's
  own list: base/typography, buttons, forms, cards, navigation,
  status indicators, progress indicators, empty/error/loading states.
