/* ============================================================
   RESTO SUITE — core theme
   Canonical design tokens + shared components. Every module reads
   these tokens; nothing hardcodes brand values. JS (LP.applyTheme)
   overrides these on :root at boot from the tenant config/preset.
   Components are lp-* prefixed so loading this file never collides
   with a module's own legacy classes during retrofit.
