   OUTBOUNDRY · FREE TOOLS
   Shared styles for the embeddable tool widgets (.obx-tool) + the tool-page
   layout chrome (hero, stage, how-it-works, related, hub grid).
   Widget palette tracks the Outboundry brand (purple #e96321).
   The .obx-tool wrapper uses all:initial so widgets never inherit theme drift.
