tourmaline v0.1.0 — AT Protocol scrobble analyser with share-to-Bluesky

Released tourmaline v0.1.0. A Teal.fm scrobble analyser that reads fm.teal.alpha.feed.play records from any PDS and builds a listener personality profile. What it does: - Resolves any Bluesky handle or AT Protocol DID to a PDS URL via Slingshot - Fetches Teal.fm scrobbles page by page with incremental loading - Aggregates top artists, tracks, albums, daily counts, genre profiles, mood mapping, era preference, diversity scoring, and obscurity indexing - Enriches top artists with genre data from MusicBrainz, listener counts from Last.fm, and images from Deezer - Caches scrobbles in both IndexedDB (client) and SQLite (server) for fast revisits - Builds a personality archetype from genre/mood/intensity/obscurity signals (e.g. "Voltage Chaser", "Midnight Librarian", "Sonic Omnivore") - Generates a personality profile card SVG and shares it as a PNG attached to a Bluesky post with a proper @ewancroft.uk mention Share flow: The only write operation. Uses @atproto/oauth-client-browser with granular scope (atproto repo:app.bsky.feed.post blob:image/png). The share button stores personality data in sessionStorage and redirects to /share, which handles the OAuth handshake and posts the image with RichText facet resolution. Colour palette: Chrome tourmaline green (#4ade80) on dark backgrounds with green undertone (#0a0f0a). Named after the mineral — tourmaline is pleochroic, showing different colours from different angles. Stack: SvelteKit 5 + Svelte 5 + Tailwind CSS 4 + TypeScript. Chart.js for genre, mood, and era visualisations. Vercel deployment.
