/* ============================================================================
   CanopyFlow — Student Pattern Planner
   Presentation layer, rebuilt as a single coherent Apple-HIG design system.

   Architecture
     1.  Design tokens        — semantic --ui-* palette (light / dark / auto)
     2.  Base & typography
     3.  Map chrome           — MapLibre, markers, route overlays
     4.  Inspector shell      — controls column, nav, sheet, drawer handle
     5.  Cards & controls     — panels, buttons, inputs, switches, sliders
     6.  Wind section         — instruments, readout, tier grid
     7.  Pattern / Canopy / Brief sections
     8.  Floating map chrome  — DZ / recenter / GPS / more, menus, legend
     9.  Overlays             — DZ picker, modals, welcome, terms, focus, toast
     10. Layout breakpoints   — ≤699 compact · 700–1099 medium · ≥1100 expanded
     11. Accessibility media  — reduced motion / transparency / forced colors

   Contracts enforced by tests/theme-css.test.mjs and tests/ui-shell.test.mjs:
     · glass (backdrop-filter) only on the floating chrome whitelist
     · every letter-spacing declaration is exactly 0
     · 44px minimum touch targets
     · exact sheet snap heights (112px / 54dvh / 100dvh − 72px)
     · exact breakpoint set (699 / 700–1099 / 1100 / 1600)
