/* theme.css -- the shared design system for the sz_sqlrunner_ws pages.

 * must look like one product, and three copies of a palette drift apart the moment
 * one of them is touched. Everything here is chrome they share -- tokens, layout,
 * typography, buttons, fields, the copy affordance, code and table surfaces. What a
 * page needs beyond this goes in that page's own <style>.
 *
 * Still no build step and no external origin: one extra local request, and the
