Add a <meta name="darkreader-lock"> tag to prevent Dark Reader from altering the docs styling. Adjust client-side routing so only '/' is replaced with the 'start' tab; unknown paths now open the 'notfound' tab instead of being redirected to start.
Add a new docs/about page (docs/docs.html) with site header/footer and basic About layout. Expand the Docs tab in docs/index.html with a Features section, General Information, and Sources table (including a link to the server repo and usage notes). Update docs/main.css to add styles for .sources-text, .docs-grid, .docs-tips and headings to support the new documentation layout and improve visual presentation.
Merge API and About pages into a single SPA-style index: removed docs/about.html and docs/api.html and moved their content into docs/index.html as tabbed sections (start, api, docs, notfound). Add client-side routing and history handling via a new script to support deep links and pushState, plus a Netlify-style docs/_redirects rule to serve index for all routes. Update styles in docs/main.css to target the new tab UI (.tab, .tablinks, .logo-text) and add styles for the 404 view. Minor markup and layout tweaks (images, buttons, response examples) to match the consolidated page.
