You are working on the anky-monorepo — a Rust/Axum server that processes
8-minute stream-of-consciousness writing sessions and reflects them back
as AI-generated images + text stories.

Read CLAUDE.md and skills.md first to understand the codebase conventions.
Then read these files in full before writing any code:
  - Cargo.toml
  - src/config.rs
  - src/pipeline/image_gen.rs
  - src/db/queries.rs
  - src/db/migrations.rs
  - src/routes/api.rs

## What we are building

The server runs on Poiesis (dual RTX 4090s, Puerto Varas, Chile, on
Starlink). It generates images locally via Flux LoRA. The problem: it
must NEVER serve these images directly — Starlink upload bandwidth is
limited and latency is high for concurrent users.

The solution: immediately after an image is generated, push it to
Cloudflare R2 (S3-compatible, zero egress fees), convert to WebP first,
and store only the CDN URL. The .anky story format (defined below) is then
assembled with those CDN URLs and stored. The client always fetches images
from Cloudflare's edge, never from Poiesis.
