/* feld.ai brand layer for Use Case Erstbewertung (Machbarkeit und Ökonomie).
 *
 * Tokens mirror feld-ai/web src/styles/_variables.scss and the fonts and logos
 * come from feld-ai/web public/ (complete Inter and IBM Plex Mono, so arrows,
 * ≈ and ✓ are covered). Run `python3 tools/sync_brand.py --check` after a
 * style-guide change; tests/test_brand.py fails when a token drifts.
 * Everything is self-hosted: no font or asset is loaded from a third party.
