/* NeoAI Platform Portal -- the Platform Plane UI (platform.neosolenergy.com).
   Same product family as the Customer Portal (apps/customer-portal): the same tokens, card, tile, table,
   badge and state vocabulary, copied (never imported -- the apps do not share runtime code across planes).
   A separate stylesheet, not an inline <style>, so the Content-Security-Policy needs no 'unsafe-inline'
   (security policy S16/S18; docs/platform-portal/security-policy.md). */
