Build me a short-link service that can fire a tracking pixel before it redirects.

STACK
- One small Node process behind my own domain
- SQLite, one table for links and one for clicks

THE REDIRECT
- GET /:code answers with a tiny HTML page, not a 301, when the link has pixels attached
- That page fires the configured pixels and then sets location.replace to the target
- With no pixels attached, answer 301 and skip the page entirely
- A meta refresh and a noscript link, so the redirect still happens without JavaScript

PIXELS
- Per link, a list of {network, id}
- Ship two to start with and make adding a third a data change, not a code change
- Refuse to save an id that does not match that network's format

BIO PAGE
- One page per handle: avatar, a line of text, and a list of links
- Rendered from a single JSON record, no editor

DEEP LINKS
- Per link, an optional iOS and Android URI
- Sniff the platform from the client hints, fall back to the web URL, and always leave a visible link out

COUNTING
- One row per click with timestamp, referrer host and a coarse device bucket
- No raw IP, no raw user agent

CONSENT
- A pixel only fires when a consent cookie says so; without it, redirect straight through

Include the schema and a README on the DNS and the consent behaviour.
