ProfessorNovaandClaude Opus 5 784b76baf7 Pablan, as it stands
Self-hosted knowledge management for SMEs: a split-screen Markdown editor
whose sections an LLM refines while you write, and RAG question answering
over the documents that result. FastAPI + Postgres/pgvector on the back,
SvelteKit on the front, everything OpenAI-compatible and self-hostable.

Squashed into a single commit; the development history stays local.

Svelte

<script lang="ts">
// Renders streamed model output token-by-token with a fade-in, the way the
// Claude web UI does: each arriving token materialises instead of snapping
// in. Every token is its own keyed span, so Svelte mounts only the newest
// one per update and its fade plays exactly once — re-rendering the whole
// Markdown string on each token (what {@html} does) would replay every
// element's animation and flicker.
//
// This is plain text on purpose: it is the transient streaming view. The
// caller swaps to the sanitizing <Markdown> renderer once the turn settles,
// so formatting still arrives — just at the end, without mid-stream reflow.
