Add global letter-spacing and typography defaults

[pedromenezes1]

Aligns the docs site's base typography with the Dashboard's global defaults:

• Add letter-spacing: -0.01em globally on html (matches Dashboard)
• Add line-height: 1.5 globally on html
• Add font-feature-settings: 'cv02', 'cv03', 'cv04', 'calt' for Inter's open numerals and contextual alternates
• Remove invalid font-display: optional from html (only works inside @font-face)
• Add tracking-tight to page titles (DocLayout, PageHeader, StickyDocHeader, Heading)
• Reset letter-spacing and line-height in HomeGrid demo tiles so kumo components render with their own spacing
• Add monospace tracking reset (letter-spacing: normal) for pre, code, kbd, .font-mono

I've reviewed all the changes in PR #425. Here's my analysis:

Summary

This PR aligns the docs site's base typography with the Dashboard's global defaults. The changes are clean, focused, and follow the project's conventions.

Changes Reviewed

1. global.css - Core typography changes

• ✅ Added letter-spacing: -0.01em globally on html (matches Dashboard)
• ✅ Added line-height: 1.5 globally on html
• ✅ Added font-feature-settings: 'cv02', 'cv03', 'cv04', 'calt' for Inter's open numerals and contextual alternates
• ✅ Correctly removed invalid font-display: optional from html (this only works inside @font-face)
• ✅ Added monospace tracking reset (letter-spacing: normal) for pre, code, kbd, .font-mono

2. Component title updates - Added tracking-tight

• ✅ Heading.astro - Headings now have tighter tracking
• ✅ StickyDocHeader.tsx - Both sticky title instances
• ✅ page-header.tsx - Page header h1
• ✅ DocLayout.astro - Main page title

3. HomeGrid.tsx - Demo tile reset

• ✅ Added tracking-normal leading-normal to demo tile wrapper (line 659) to reset global typography so kumo components render with their own intended spacing

Visual Regression Results

The visual regression report shows 27 screenshots with minor changes (mostly <1% pixel difference), which is expected and acceptable for typography adjustments. The changes are subtle and align with the Dashboard's design system.

Code Quality

• Follows the project's CSS conventions
• Properly resets typography in component demo areas to prevent unintended inheritance
• Correctly fixes the invalid font-display property placement

This PR looks good to me and is ready to merge. The typography changes are well-considered and the implementation properly handles the cascade/reset pattern for component demos.
