   Strong Password Generator - stylesheet

   Theme: same dark design tokens as the site's other standalone tools
   (see typing-speed-analyser/assets/css/style.css) so this tool shares a
   consistent look, without any cross-project file dependency - every
   token and rule below is self-contained in this file. Unlike the typing
   tool's locked single-viewport app shell, this page is a normal
   scrolling page (a generator card plus settings plus informational
   content), so the layout section below is written from scratch for
   that shape.

   Architecture:
     1. Custom properties (design tokens)
     2. Reset / base
     3. Topbar
     4. Page shell / hero
     5. Cards (generator, settings, multiple-password)
     6. Password display + strength meter + analysis
     7. Form controls (length, toggles, presets)
     8. Buttons
     9. Multiple-password results
     10. Informational sections + FAQ
     11. Footer
     12. Responsive breakpoints
     13. Reduced motion / forced colors
     14. Scrollbar
