   Shared navigation primitives (nav links, nav buttons, brand, mobile
   drawer, bottom tab bar, focus rings) extracted into one place so the
   authenticated (DxMenu) and public (<a> links) navs share one visual
   language. Populated in Phase 0.4.

   Colors route through tokens:
     - text          -> --dxds-color-content-neutral-default-rest (adapts to dark mode)
     - accent/hover  -> var(--theme-accent-color, var(--sos-accent))
     - glows         -> color-mix(in srgb, var(--sos-accent) X%, transparent)
     - shadows       -> --sos-shadow-md / --sos-shadow-lg
