/*
  Stiftungs-Designsystem — respektTiere!
  ======================================
  Use ONLY these tokens and patterns. Avoid one-off spacing,
  font-sizes, or text-align overrides in components.

  SPACING (vertical & gaps)
  -------------------------
  --space-1  0.5rem   tight (icon gaps, meta)
  --space-2  0.75rem  compact (card internal)
  --space-3  1.25rem  default (paragraph → heading)
  --space-4  2rem     group (between related blocks)
  --space-5  3rem     section padding (mobile+)
  --space-6  4rem     section padding (desktop)

  Section rhythm: every major band uses
    padding-block: var(--space-section)
    border-top: var(--rule)
  Do not mix custom paddings on sections.

  TYPOGRAPHY
  ----------
  --text-body   body copy
  --text-lede   intro / supporting
  --text-small  meta, captions, roles
  --text-h1     page title
  --text-h2     section title
  --text-h3     card / person title
  --text-brand  home brand wordmark

  Headings: Newsreader. Body: Figtree.
  Line-height body 1.65, headings 1.2.

  ALIGNMENT
  ---------
  Default: left. Never center or right-align page content
  unless a utility class is explicitly applied.

  LAYOUT WIDTHS
  -------------
  --width-page    outer shell
  --width-measure readable text measure
