   Star-Touched Legacy layout: top nav bar, desktop only (1024px+)
   The header (brand/weather/currencies/bell/avatar) is untouched: only
   `.site-sidebar` is retired for this one theme, restyled from a left rail
   into a horizontal strip under the header. This is a pure restyle of the
   EXISTING `.sidebar-nav` markup from base.html: same links, same URLs, same
   badges, same <details> groups. Below 1024px this theme is identical to
   every other theme (the sidebar is already hidden in favor of the bottom
   tab bar, per the rule just above).
   The interface-style exclusion is intentional: UserPreferences keeps the
   Legacy palette selection when a player switches to Frontier, but the
   Legacy palette's alternate layout must not reshape the Frontier shell. The
   Classic interface is excluded too: it shares this palette's menubar markup
   (base.html's menubar_nav flag) but brings its own menubar styling, and the
   two rule sets would otherwise stack.
