/* ==========================================================================
   Hearth: sayhearth.com
   A fork of steady-site's system: the same paper, ink, Georgia, named-line grid,
   theme toggle and rise motion, with Hearth's sage accent. The tokens are spec section 6,
   plus the -ink shades from the design board (design/index.html :root) for small
   text on paper. No webfonts and no build step; the CSP allows this origin only.
   Order: tokens, base, type, the spread, header, buttons and lists, footer, legal
   pages, motion and material, print. Task 4 appends the landing page and Task 7
   the invite page.
