style: serve Lora locally, lighten bg, bump article font size

- Download Lora (400/700, normal/italic, latin+ext) via @fontsource
  and serve from /fonts/ — no Google Fonts dependency
- Lighten light-mode background surface-50: #fefcf0 → #fffef5
- Give widgets and post-cards bg-surface-100 so they read as
  cards against the lighter canvas (brennan.day panel style)
- Nudge prose-lg base size: 1.125rem → 1.175rem with lh 1.8
