1// Package gallery is the platform's gnoweb face (design §2.5.7): the
2// product stays browsable on gno.land even without the website. It is
3// private (re-deployable in place), read-only and holds nothing.
4//
5// Routes:
6//
7// "" latest collections
8// c/<cid>[?page=N] one collection, 20 tokens per page
9// c/<cid>/t/<tid> one token: art, traits, owner, listing, provenance
10// e/<engine pkgpath> an engine's manifest and status
11// u/<name> a registered user's collections and listings
12//
13// Every user-supplied string goes through p/nt/markdown/sanitize (RA M-9);
14// every list is paginated.
