/* =====================================================================
   RAYPCB Tools — "Instrument" shell design system  v3.0
   ---------------------------------------------------------------------
   One visual language for all 301 tools (RF engine .pcbs-* and PCB
   engine .ray-*). Loads last, so it restyles both engines at once.

   It also repairs a real bug: the PCB engine's design tokens were only
   declared on .raypcb-tool, while the plugin renders .pcbsync-tool, so
   every `var(--ray-*)` resolved to nothing and all borders, card
   backgrounds and input outlines silently dropped out. The token
   bridge below re-declares them on every container.
