/* Veridon Chassis dashboard — terse, info-dense, mobile-first.
 *
 * Brand: Decision-Grade (D3) — light mode primary. Off-white surface
 * (#FAFAF9), graphite ink (#1B1E23), steel-blue accent (#3D5A80).
 * Matches the Chassis marketing site (docs/rebrand-research/chassis-
 * preview.html) so the operator dashboard and the public landing page
 * read as one product.
 *
 * Typography: Geist Sans (display) + Inter (body) + JetBrains Mono /
 * Geist Mono. Tabular figures everywhere. Tight 4/6/8 px radius scale,
 * hairline borders, minimal shadow. Engineered restraint, document-grade.
 *
 * Spec: ~/Code/jarvis-server/docs/rebrand-research/chassis-visual-spec.md
 *       ~/Code/jarvis-server/docs/rebrand-research/chassis-preview.html
 *
 * If you change a color here, also check:
 *   - Chassis iOS Theme.swift (must stay aligned within +/- a shade)
 *   - docs/rebrand-research/chassis-visual-spec.md (canonical reference)
