feat: Step 2 - Mantine UI & grayscale theme
Integrate Mantine UI library and configure grayscale dark theme:
- Created postcss.config.mjs with Mantine preset and breakpoints
- Created app/theme.ts with custom 10-shade grayscale palette
- Configured dark mode enforcement (forceColorScheme)
- Set default component props for consistent styling:
- Buttons: filled variant, gray color, xl radius
- Paper: border, shadow, md radius, gray background
- TextInput/Textarea: filled variant, rounded radius
- Updated app/globals.css to import Mantine core styles
- Updated app/layout.tsx with MantineProvider and ColorSchemeScript
- Updated app/page.tsx to use Mantine components (Center, Paper, Stack, Title, Button)
Theme achieves the "minimal, grayscale, unstyled" aesthetic with:
- 10-shade custom gray palette (ponderGray)
- Dark mode enforced via forceColorScheme
- Darkest gray background (#181a1d)
- Lightest gray text (#e9ecef)
- Consistent rounded corners and spacing
Tests: Verified Mantine theme applied correctly with rounded button corners and Paper component with border
Status: ✓ 2 tests passed (8.4s, 7.1s)
