The submit form now resolves a pasted input two ways: a known record (at://
or a recognized app URL) takes the record path — gated to the round's
acceptedSubmissionTypes and fetched for its CID — while any other http(s)
link becomes a plain `url` deliverable. resolveSubmissionInput keeps known
hosts on the record path so a transient resolution failure can't silently
downgrade a record to a url. The hint copy names both paths, keeping payload
primary and the url an explicit fallback. Tests cover the new branches.

A submission's deliverable is now a gradient, not a single shape: payload
(preferred — a content-addressed strong-ref to a record on another app) or
url (fallback — a plain link, for work not yet on ATProto). Both are optional
in the schema since Lexicon can't express "one-of" across fields; the
"at least one" rule lives in code as Submission.getDeliverable — the single
gate all rendering/validation flows through, keeping payload primary and the
record-vs-link difference visible. Read-side (payload-preview + round detail)
routes through the gate; url submissions render as a visibly weaker link.
Docs + API reference updated; unit tests cover the gate. Submit-form url
input and re-publishing the lexicon are follow-ups.

Replace the flat category list with a guided story built on the transit-line
vocabulary. Lifecycle and timeline rounds render as live subway diagrams (the
now-dot's position IS the derived state), gating gets a join-mode triptych, and
a legend teaches the visual language up front — hairline rows replace the
off-brand bordered boxes.

Lead with a real adopter: EPTSS's live "Round 29" (song as subject,
fm.plyr.track submissions), pulled from the known-organizer DID and kept out of
the test-data heuristics. Annotate the documented "reads OPEN with no
submission-deadline" gotcha inline wherever it occurs (Round 29 and the test
gotcha scenario). Loader + categorize unchanged; the transit lines are pure
functions of round.value, so the only added fetch is EPTSS itself.

New /docs/built-on (TSX route + markdown mirror): a truthful "in the wild"
adopters table (the atjam.at app itself + EPTSS) plus an end-to-end worked
example mapping a judged, votable game jam — the rpg.actor shape — onto the
at.atjam.* spine. It shows the two illustrative actor.rpg.* lexicons an
adopter would publish under their own namespace, the round wired through the
extension points, and vote tallying via the existing Queries.getBacklinks
substrate. Explicit callout that rpg.actor does not actually run on atjam.
Wired into the docs sidebar, the overview list, and the footer.

Lead the mental-model/explanation prose with what the lexicons ARE — the
five at.atjam.* schemas published as com.atproto.lexicon.schema records,
resolvable via the _lexicon.atjam.at DNS record — plus the resolve-then-
codegen workflow (goat / @atproto/lexicon-resolver). Demote the
"not on npm" caveat to a closing aside. Swap the obscure com.whtwnd.blog.entry
deliverable example for the cross-app site.standard.document standard, and
tighten the "no central database" bullet. Mirrors kept in sync (.tsx + .md).

The repo lives on Tangled now, not GitHub. Replace the placeholder
github.com/natespilman/atjam links: the docs' source links (GH → a
Tangled-based REPO plus repoFile/RepoFile helpers), the footer "source" link,
and the lexicon/terms/privacy footers; linkify source-file references in the
docs pages. The external @atcute library link is left as-is.

Inline file-path mentions in the developer docs now link to the file on
Tangled (the repo's home), matching the TSX pages.
