 * HTML Cleaner & Markup Sanitizer — module-scoped styling.

 * Brand-focused redesign with:
 * - Brand color #026ed0 for primary actions and accents
 * - Alternating section backgrounds (white + ultra-light blue tint)
 * - Subtle borders instead of heavy shadows
 * - Left accent bars for key areas
 * - Reduced whitespace, increased density
 * - Clean, professional, lightweight aesthetic
