scaffold: 12 Hobbies Studio site + OpenScribe project page

Initial static site (no framework, no build) for the 12 Hobbies Studio maker
studio, featuring OpenScribe as the flagship project.

What changed:
- index.html: studio home - hero, featured OpenScribe block with sync diagram,
  projects grid, about. British spelling, dark warm theme.
- projects/openscribe.html: OpenScribe product page. Leads with the "bring your
  own AI" differentiator, an interactive provider picker, the feature set, a
  four-step build guide, and licensing.
- assets/styles.css: all styling (palette, cards, featured layout, picker, code blocks).
- assets/app.js: dependency-free provider picker that swaps a sample server .env
  snippet across Ollama / OpenAI / Anthropic / Groq / LM Studio - on message with
  OpenScribe's any-AI design.
- README, LICENSE (MIT for site code), .gitignore.

Why:
- The user asked to develop a site on 12 Hobbies Studio; this is the first cut,
  showcasing OpenScribe and the connect-to-any-AI capability. Branding uses sensible
  defaults and is trivially editable (noted in README).

Notes:
- Pure static files; deploy to any static host or Forgejo Pages. Validated: app.js
  passes node --check; HTML section tags balanced.
