/* ---------- chrome parity with the main site ----------
 * The design system has NO element-level resets: on my2 those come from
 * bootstrap.min.css (Reboot) and style.css, which this theme deliberately does
 * not load. The header and footer are also OUTSIDE .wd-page — that class is on
 * <main> — so webdev-base.css’s `.wd-page *` border-box reset never reaches them.
 * Without the few rules below the shared chrome drifts from my2:
 *
 *   box-sizing  .wd-shell became 1320px PLUS its 48px of padding (48px too wide),
 *               and every .wd-btn added its padding outside its width, which is
 *               why the Client Area pill came out larger.
 *   body margin the browser default 8px inset the sticky header and the footer,
 *               so their bands stopped short of the viewport edge.
 *   the rest    my2’s own body rule; the chrome was designed under it.
 *
 * NOT copied from style.css: `a { outline: none !important }` (removes focus
 * rings) and `text-decoration: none !important` (would kill article links).
