/* ==========================================================================
   WarrantyGuard - application styles (Task 10).

   Loaded after Bootstrap 5.3, so everything here only fills small gaps:
   - the page fills the viewport and keeps the footer at the bottom,
   - brand colour and a few reusable card/table touches,
   - nothing that needs an inline <style> block (the CSP allows 'self' only).

   Colours use Bootstrap's CSS variables, so light and dark mode both work
   without a second rule set.
