/* Mikko Koivunalho Oy -- element defaults.
 *
 * Bare elements only, no class names, so nothing here can collide with an
 * application's own stylesheet and any of it is overridden by a single class.
 * Separate from mkoy-tokens.css because tokens are facts about the brand and
 * this file is opinions about HTML -- a static marketing site and a data-entry
 * application want the same tokens and not necessarily the same opinions.
 *
 *     <link rel="stylesheet" href="/css/mkoy-tokens.css">   <!-- always -->
 *     <link rel="stylesheet" href="/css/mkoy-base.css">     <!-- usually -->
 *     <link rel="stylesheet" href="/css/mkoy-ui.css">       <!-- app chrome -->
 *
 * This reproduces how Polmai already renders, with two exceptions, both
 * measured accessibility fixes rather than restyling: form controls are bounded
 * by --mkoy-border instead of --mkoy-hairline (1.47 contrast fails WCAG
 * 1.4.11's 3:1 for anything clickable), and there is a visible focus ring.
