/* ==========================================================================
   ApexLab Automation: shared styles
   Font notes:
   - "Codec Pro" is a commercial font with no public CDN distribution, so we
     fall back to "Space Grotesk" (Google Fonts) for headlines, which shares
     Codec Pro's geometric, tight-tracking character.
   - "Grotesk" is ambiguous (many faces share the name); we use "Inter"
     (Google Fonts) for body copy as a close, highly-legible fallback.
