/* =============================================================================
   SharperSunday design system — "The Sunday Desk"
   Source of truth for tokens, type, and the component language shared by the
   Astro site and the static landing page.

   BYTE-IDENTICAL MIRROR. This file exists twice and the two copies must never
   diverge:
       blog-astro/src/styles/system.css   (imported first by global.css)
       public/landing/system.css          (linked before landing.css)
   Parity is enforced by scripts/__tests__/systemCssParity.test.mjs. Edit one,
   copy it over the other, run that test.

   FONT LOADING IS NOT HERE. The Google Fonts <link> lives in the layout head
   (blog-astro PageLayout/HeadBase) and in public/landing/index.html — an
   @import here would serialise the font request behind this stylesheet.

   BREAKPOINTS — exactly three on the whole site. Custom properties cannot
   drive @media, so this banner is the declaration:
       560px   sm   phone to large phone
       860px   md   tablet; compact table layouts turn on at or below this
      1100px   lg   desk grid (7/5, 8/4, 4/8 splits) turns on
   Only prefers-reduced-motion queries are exempt from that list.

   RADII — 0 (tables, stamps, rules), 6px (controls), 14px (panels). Nothing
   else, ever. No drop shadows anywhere. No colour ramps.

   COLOUR RULES (guarded by scripts/checkPalette.mjs)
     - Violet (--accent) is interactive-only: links, buttons, active chips,
       focus rings, the current-row marker. Never a wash, a glow, a colour ramp,
       heading colour, or a border on something you cannot click.
     - Coral (--ai) is the AI talking, or the upgrade moment. Legal only in
       .ai-quote, .verdict-line, .transcript-ai, .pullquote-ai, .stamp-ai,
       .cta-upgrade and .handoff* — plus the :root token block. Scarcity is
       what makes it read as a voice.
     - Surfaces are rules, not boxes. --card is used for exactly two things:
       an interactive tool panel and an AI quote block.
