   FreightMath App Shell — shared collapsible sidebar + top bar (LIGHT).
   Injected by shell.js and linked by every production page. All classes
   are namespaced fms-* so they never collide with a page's own CSS.
   Uses the canonical tokens from tokens.css. Dark mode is a later phase.
   Governed by .claude/skills/spotcheck-design/SKILL.md.
