   ThemeShell's Accent="…" parameter: that parameter emits an inline
   style="--accent: …" on the shell root, which is a descendant of <html> and
   therefore beat the [data-bs-theme="dark"] override below for the whole app
   — the dark accent was dead. As a :root declaration it loses to the dark
   block (equal specificity, later in this file) and wins over theme.css
   (equal specificity, earlier sheet), so both schemes resolve correctly.
   The value matches theme.css's own light default, so light mode is

   to, override the CSS *variables* only, never the box properties, because
   .btn-group's seam and border-radius machinery is built on them. */
