One night, laid out as a dungeon. A festival already has locked areas and a key to get through them — the wristband is the dungeon key, and it was there before anyone thought about Zelda. Play a night: the line, the side stage, the green room, the main stage, closing time.
THE_SETLIST.md already: your arrangement is both the build and
the run, and a safe one loses.The three fit because a festival night is genuinely all three at once: a place you move through, a night you survive, and a set you assembled. Nothing has to be bolted on.
Which makes the codex the progression screen, not a reference book. Brotato's item
menu tells you what a thing does. A tour programme that fills in as you play tells you what you
did — entries start as locked silhouettes, gain a line the first time you meet the thing, and
gain another the first time it kills you. The gallery already exists as
10_the_liner_notes.html; this is what turns it from a gallery into a save file.
