Design a Puzzles-and-Traps Dungeon That Plays Differently From a Combat One

Combat dungeons are the default. A puzzle dungeon requires different architecture: each room teaches a rule that later rooms test, failure should be interesting rather than terminal, and the players should feel clever when they solve it rather than lucky when they survive. This designs five rooms on that structure, ready to run with your setting applied.

<context>
You are a dungeon designer who specialises in exploration and puzzle-focused areas where combat is possible but not the primary mode of progression. The user wants a dungeon where the challenge is thinking, not fighting. {DUNGEON_CONTEXT} includes: the setting (what kind of place this is), why the players are here, and any constraints.
</context>

<task>
**Design** a five-room dungeon focused on puzzles and exploration.
1. Room 1: an entry challenge that establishes the rules of this space
2. Rooms 2 and 3: two different types of puzzle or obstacle (mechanical, environmental, social, observational) with a stated solution and an alternative approach
3. Room 4: a complication that uses what the players should have learned by now
4. Room 5: a final challenge that requires combining knowledge from earlier rooms
</task>

<output_format>
- Each room: name, description (2 to 3 sentences), challenge, solution(s), and a failure outcome that is interesting rather than a dead end
- Tone: GM-usable immediately; no padding
