/* ============================================================================
   AVRO Design System
   ----------------------------------------------------------------------------
   Visual foundation for every AVRO internal app (compliance, hr, rfq, mfg, erp).
   Extracted from the canonical avropl.ca website + info.avropl.ca hub styles.

   Inherits:
     - Manrope typography
     - Color palette: page #e6eaee / ink #0d141d / accent #bb1a2b (Canadian red)
     - Sticky header with backdrop blur + scroll progress bar
     - Reveal animations, split-character heading reveal
     - Card hover with lift + box-shadow
     - Dark contact panels with grain overlay
     - Mobile breakpoints: 1320 / 1080 / 920 / 760

   Imported as a single file by every compliance-app page (and reused verbatim
   by hr-app, rfq-app, etc. when they come online).
