   Scope of this file:
     01. Design Tokens (CSS Custom Properties)
     02. Base & Typography
     03. Bootstrap Component Overrides (buttons, forms, cards, tables, etc.)
     04. Application Shell — Sidebar
     05. Application Shell — Header
     06. Application Shell — Content / Page Header / Breadcrumb
     07. Application Shell — Footer
     08. Shell Responsive Behaviour
   Reusable UI components (stat cards, timeline, avatars, auth…) live in
   style.css. No page-specific rules exist in either file.
