Add markdown blog, accessibility improvements, and homepage refinements (#5)

## Summary
- add file-based Markdown blog with front matter, static routes, and RSS
feed generation
- refine homepage project and blog sections, including clickable cards
and improved focus states
- improve accessibility/navigation behaviour (focus visibility, home
link behaviour) and add smooth in-page scrolling
- add and polish a floating back-to-top button
- integrate and refine brand mark usage (header/footer/favicon) plus
contrast/spacing polish
- update studio thesis language and refresh the Wear OS article

## Validation
- `npx pnpm test`
- `npx pnpm build`

_Fun fact_: this branch changed 2,979 lines — enough to read aloud
during a 50-minute commute, if your passengers are unusually patient.

+## Blog
+
+Blog posts live in `content/blog` as Markdown files with front matter.
+
+### Add a new post
+
+1. Copy `content/blog/_template.md` to a new file named `YYYY-MM-DD-your-slug.md`.
+2. Fill in front matter fields:
+   - `title`
+   - `date` (format: `YYYY-MM-DD`)
+   - `slug` (URL path, for example `wear-os-tauri`)
+   - `excerpt`
+   - `tags` (string array)
+   - `draft` (`true` or `false`)
+3. Write the article body in standard Markdown below the front matter.
+4. Run `pnpm build` and confirm the post appears at `/blog`.
+
+Draft behaviour:
+- `draft: true` posts are hidden in production builds.
+- Draft posts still appear during local development.
+
+RSS feed:
+- Generated at build time to `public/blog/feed.xml`.
+- Published URL: `/blog/feed.xml`.
+- Override site URL by setting `SITE_URL` during build (default: `https://liminalhq.ca`).
