/* ══════════════════════════════════════════════════════════════
   daily10-v3.css — The Daily 10 case study, from Figma "Daily 10 Case Study" (node 5548:5839).
   A 672px reading column centred on the page; a sticky sidebar on the left with a reading-progress
   bar, a back button, the section nav (current section = blue pill) and other projects.
   Type: Cormorant Garamond for the title, Albert Sans for everything else (as in the design).
   Narrow screens: the sidebar goes, a slim progress bar sits under the header instead, and the
   other projects move to the end of the page.
