Redesign book interior: Illuminated Nocturne aesthetic

Replaces Georgia + per-story color theming with a unified premium
fairytale look: Cormorant Garamond (display/titles) + Lora (body),
warm cream text pages (#faf8f2 with paper noise texture), deep ink
typography (#1e1b18) throughout — no per-story text color variation.

- fonts/: committed WOFF2 files via @fontsource packages; auto-copied
  by scripts/setup-fonts.js (runs as postinstall)
- Typography: story number in small caps, hairline rule, ❧ ornament
- Layout: cream background replaces per-story bg, radial glow on title
- build.js: passes frontMatter (author, year) to templates
- Templates: author byline on title page, cleaner imprint page
