feat(web): Pressing Plant design tokens + self-hosted Fraunces

globals.css defines the manila/spruce palette as CSS custom properties for
both themes (prefers-color-scheme + explicit data-theme override), paper
grain, base reset, focus-visible, reduced-motion. Fraunces vendored as woff2
and wired via next/font/local with a Palatino/Georgia fallback.
