   FRANKLIN YARD — CORE BRAND STYLESHEET
   Foundation: all design tokens + components shared across every system.

   ARCHITECTURE
   This file alone is NOT enough. Always load it alongside one overlay:
     <link rel="stylesheet" href="fy-core.css">
     <link rel="stylesheet" href="fy-utility.css">    -- OR --
     <link rel="stylesheet" href="fy-editorial.css">  -- OR --
     <link rel="stylesheet" href="fy-teaching.css">

   - fy-utility.css   → dashboards, services pages, internal tools, dense UIs
   - fy-editorial.css → marketing site, manifesto pages, hero moments
   - fy-teaching.css  → student-facing curriculum (white field, rounded)

   The overlays define H1 and H2 (which differ across systems) and any system-
   specific overrides. Everything else is here.

   For voice / tone / copy rules, see fy-voice.md.

   THE NON-NEGOTIABLE RULES
   - Bone is the page (white in teaching system only).
   - White is a material, NOT a field. Use it for cards, tiles, receipts.
   - Magenta is a signature, not a decoration. CTAs and accents only.
     One magenta moment per page, tops. Never as default heading text.
   - Don't italicize AND color magenta on the same word — pick one.
   - Sentence case everywhere except a hero moment.
   - One Caveat note per page maximum.
   - Stick to ONE header family per page. Don't mix serif and sans at H1/H2.
