How it was set up the first time (21 Oct), for reference:
Make a new project on itch. Title: Hullbound. Project URL: hullbound.
Short description: Take a crew to a far port on a ship you draw. Every voyage is an episode, written from your choices. (23 Oct; was the starship you draw and a choice at every base)
Kind of project: HTML. Release status: In development. Pricing: $0 or donate, with a suggested donation of $3.99. (Changed 23 Oct. Not "No payments": Shipwright on the web is a donation of $3.99 or more on this page, and No payments turns donations off.)
Uploads: hullbound-itch.zip, tick "This file will be played in the browser".
Embed options: 820 x 760. Tick Mobile friendly, Fullscreen button, and Automatically start on page load.
Description: tap Copy below and paste it in. (21 Oct, later: one new line about the music. Paste the whole thing again over the old one.)
AI disclosure: Yes, tick Graphics, Code and Text. The ship on the logo is from an image model (gpt-image-1); the name on it is set in a font by code. The cover and banner painting is from the same image model, with the words set by code. Everything in the game is drawn by its code, and the screenshots are screenshots of the game.

Screenshots, in this order
desk-episode.png: Episode 1 of Season 1: a courier with a sealed case asks for passage, three minutes in. (23 Oct, first)
desk-stop.png: Docked at a base: a passenger asks to come aboard.
desk-arrive.png: Arrived at the port: the voyage record, the yard's pay, where next.
phone-away.png: On a phone, back after 30 hours: what happened, by name.
desk-raid.png: Raiders aboard (red); the bridge saw them and the crew sheltered (pink).
desk-build.png: Building: a new room drawn under the corridor.
The grown ship and the 30 hours away were reached by running the game's own sim faster than real time. A new player starts on the small ship in the phone shot.
Logo
