/* ==========================================================================
   Zero to Rank — main.css
   Layout and type follow the Markethon system, in Zero to Rank's colours:
   - Type: Bricolage Grotesque (display), Manrope (body), Instrument Serif
     italic (emphasis) and JetBrains Mono (labels). All self-hosted.
   - Colour: brand blue #0593C6 on a cool white base #FCFFFF. Dark sections are
     a deep night blue lit by navy and indigo glows, with ice blue #6FD6F7 as
     the signal colour. The hero keeps its own blue gradient.
   - Rhythm: blue hero → blue ticker → light sections with dark feature cards
     → dark case-study and process bands → dark CTA box → dark footer.
   Everything is scoped under .ztr (or body.ztr-landing).
