Gotchas
Sign-in is Google-only, so the listing is tied to a Google identity whether you want that or not. Set the profile name deliberately, because it becomes your public byline.
Upvotes silently fail until your founder profile has a name and bio saved. Nothing tells you this: the counter just stays at 0 of 2 no matter how many times you click.
The badge snippet contains the placeholder "your-product" until you type your product name into the form. Copy it too early and you deploy a badge pointing at nothing.
Saving the product does not enter it. The dashboard shows "Not Entered" and you have to click Schedule Launch and then Enter Gameweek separately.
The quest counters on the submit form do not live-update. Their Refresh button did not help; only a full page reload showed the completed quests, and reloading loses everything you had typed.
Entries are for the upcoming week only, with no mid-week entry, and finishing in the top 20 forces a one-week cooling-off before you can enter again.
