   Explain8 core stylesheet. Hand-written, no build step.
   World: the edit suite. Navy suite grounds, electric-blue actions and
   playhead, condensed Bricolage display at poster scale, square controls,
   surfaces separated by tone steps rather than rules.

   Contents
     1  Fonts and tokens
     2  Base, typography, browser surfaces
     3  Layout primitives (.container .section .grid .stack ...)
     4  Buttons and links
     5  Forms (.field)
     6  Notices, badges, tabs, tables, accordion, link index
     7  Site header and navigation
