 * Spry CSS — a light, no-JavaScript CSS framework of utilities and components.

 * Optional companion to the Spry web application framework.
 * Core + default theme in one file. Themes live in themes/*.css and are
 * activated with <html data-theme="name"> (or the #spry-theme-* radio hooks

 * Color mode: <html data-mode="light|dark"> (omit for auto).

   Palette blocks use :where() so their specificity is (0,0,0): any active
   theme scope (attribute or radio hook) overrides them, including the dark
   blocks below. Themes can therefore be "fully light" and ignore dark mode.
