   Personal Inventory Manager — design system
   Layered on top of Bootstrap 5.3 (which already ships dark-mode variables
   via [data-bs-theme]). This file restyles Bootstrap's own primitives rather
   than replacing them, and adds the sidebar/topbar app shell + a few small
   components (stat tiles, theme toggle) that Bootstrap doesn't provide.
