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.

+# 12 Hobbies Studio - website
+
+A small, dependency-free static site for **12 Hobbies Studio**, a maker studio that builds
+open-source, self-hostable projects. The flagship project featured here is
+[OpenScribe](https://git.discworld.casa/laurence/openscribe), an open AI voice recorder you
+can connect to any AI.
+
+> Note on branding: this is an initial site with sensible defaults (name, tagline, colours,
+> copy). All of it is easy to change - edit `assets/styles.css` for the look and the HTML for
+> the words. Nothing here is locked in.
+
+## What's here
+
+```
+index.html              Studio home: hero, featured project, projects grid, about
+projects/openscribe.html  OpenScribe product page + interactive "bring your own AI" picker
+assets/styles.css       All styling (no framework, no build)
+assets/app.js           Provider picker that swaps a sample server .env snippet
+```
+
+## Preview locally
+
+It is plain HTML/CSS/JS - open `index.html` in a browser, or serve the folder:
+
+```bash
+python -m http.server 8080   # then visit http://localhost:8080
+```
+
+## Deploy
+
+Any static host works (it is just files). For Forgejo Pages, publish this repo per your
+instance's Pages setup; for a plain web server, copy the files to the web root. There is no
+build step and no server-side code.
+
+## Licence
+
+Site code (HTML/CSS/JS) is MIT (see `LICENSE`). Prose content is the studio's own.
+OpenScribe is an independent project inspired by the Plaud class of device and is not
+affiliated with Plaud.
