/*
 * v6-shell.css — JYB unified SPA shell visual layer (wave-2-rev2).
 *
 * Loaded by app-shell.html AFTER tokens.css / components.css / tri-web-
 * layout.css / tri-web-surface.css. Adds shell-specific tokens and
 * .jyb-shell__* selectors. Does NOT redeclare existing tokens or
 * override per-page polish layers.
 *
 * Tri-web breakpoints (matches tri-web-layout.css):
 *   <=768  mobile  : sidebar off-canvas; bottom-nav fixed; main is single-col
 *   769-1024 tablet: collapsible sidebar (off-canvas), no bottom-nav
 *   >=1025 desktop : fixed sidebar 248px, no bottom-nav
 *
 * Touch target floor (mobile/tablet): 44px (WCAG 2.5.5 / iOS HIG).
 *
 * Wave-2-rev2 expansion (lines 427+):
 *   - token aliases: color / type / shadow / density (reuses --jyb-* base)
 *   - 9 standardized components: btn / card / alert / empty / loading /
 *     toast / table / form-field / modal
 *   - per-route layout hooks: cw / dy / ref / nb / up / settings
 *   - prefers-reduced-motion overrides
