Subject: [PATCH] fix: replace Tailwind v4 CSS syntax with v3 directives in
 index.css
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The project uses Tailwind v3 (package.json: "tailwindcss": "^3.4.11") but
index.css was using Tailwind v4 CSS-first syntax:
- @import "tailwindcss" → replaced with @tailwind base/components/utilities
- @import "tw-animate-css" → removed (not installed; tailwindcss-animate v3 is used instead)
- @custom-variant dark → removed (v4 only)
- @theme inline { ... } → removed (v4 only; config already in tailwind.config.ts)
- @utility container → removed (v4 only; config already in tailwind.config.ts)

Also fixed CSS variable format: removed hsl() wrappers from variable values
since tailwind.config.ts already wraps them as hsl(var(--name)).

Fixed --sidebar → --sidebar-background to match tailwind.config.ts.
