/* =====================================================================
   FreightMath SpotCheck — Canonical Shared COMPONENT Styles
   SINGLE SOURCE OF TRUTH for the core component library (reset, body,
   header/nav, cards, forms, buttons, layout, results-sidebar core).

   Linked by ALL FOUR pages (index, trip-check, spot-check, dashboard) as
   the canonical component base. trip-check/spot-check match it exactly;
   index/dashboard have been converged to it and keep only a few
   INTENTIONAL inline overrides (documented in each page and in the skill,
   e.g. index's .card margin-bottom and its .btn-config-composed primary
   button). Before linking this file into a NEW page, audit the overlap:
   any inline rule that shadows a selector here must be a deliberate,
   documented override — never accidental drift (unoverridden properties
   such as label text-transform would otherwise leak in).

   Design tokens live in tokens.css (linked by every page).
   Governed by .claude/skills/spotcheck-design/SKILL.md.
