/* MCDDD web shell.
 *
 * Accessibility is a requirement here, not a polish pass: dark by default,
 * text that scales with the browser's own font size, contrast measured against
 * WCAG AAA (7:1 for body text), visible focus on every interactive element,
 * and nothing conveyed by colour alone.
 *
 * The report itself is rendered by mcddd/htmlreport.py, which brings its own
 * theme switch, text-size controls and read-aloud panel. This file styles only
 * the shell around it, and deliberately uses the same palette so the two do not
 * fight each other.
