/* ============================================================================
   CONTENT — pages, blog and FAQ (Phase 14)
   ============================================================================
   Nothing here introduces a colour, a font, a spacing step or a breakpoint.
   Every value is a token from the design system, because a blog that invents
   its own type scale is a second design system with one page in it.

   The reading measure is the one decision this file makes that the rest of the
   site does not need: an article read straight through wants a narrower column
   than a grid of product cards, so `.content-page` is capped at 68 characters
   rather than at the container width.
   ============================================================================ */
