/* ============================================================
   UI/UX Nest — Case Study
   Design system: "The Syllabus"
   A field-notebook / course-catalog identity — the one project
   on the site that's actually a sequence (a curriculum), so
   numbered structure is earned here instead of decorative.
   The signature motif is the scope ledger: a kept/cut tally
   that makes the scope-creep tension visible and literal.

   Palette: blueish-white canvas with deep teal (#06405A) as
   the dominant structural ink — headlines, nav, body text,
   links — paired with a deep sage as the one accent reserved
   for anything kept or carried forward in the project. Teal
   doubles as the signal for anything cut or deferred, so the
   kept/cut tension reads as sage-vs-teal everywhere it shows
   up, not just inside the ledger itself.
