   grow.myflowchamp.com — section stylesheet
   ----------------------------------------------------------------------------
   This file holds LAYOUT and COMPONENTS only. Every colour, radius, shadow,
   spacing step and font comes from the main site's token file, which is
   <link>ed ahead of this one. No token value is ever duplicated here — if a
   value needs to change, it changes in tokens-daylight.css and this section
   follows automatically.

   Chrome is always LIGHT (Daylight Focus). The learning modules render in
   their own dark theme inside an iframe; see .module-frame, which is
   deliberately styled as a dark "canvas" so the switch reads as intentional
   framing rather than a broken page.
