/*
 * shell.css — the Rams chrome (UI-SPEC §Shell Layout & Register Bands).
 * -----------------------------------------------------------------------
 * Every value is a token reference (var(--color-*) / var(--spacing-*) /
 * var(--type-*)); the only literals are the machined-border geometry the
 * UI-SPEC enumerates (1px/2px rules, 8px lamp/gantry/notch, 40x40 plate,
 -2px hit slop, 320px card max-width, 20px dot as SVG r=10; Phase 5 adds:
 chip plate 28px tall + -8px hit slop (44px target), origin ring 24px/2px,
 destination pin 12px square + 3px×8px tail (20px glyph), route line
 widths 9/5/3 map-space paint, the 64px control-clearance composite,
 160px name-chip max-width, 3px focus bracket). Zero
 * roundedness (the one `border-radius: 0` reset pins MapLibre's chrome),
 * zero transition/animation — state changes are instant hard swaps.
 *
 * D-10 / PX-02: NO MapLibre rule participates in theme slots. The map
 * style is Rams-constant; only --shell-bg / --shell-on-surface re-slot
 * behind [data-tg-theme].
