# Archetype: odd_one_out

The question must list 4 items and ask WHICH ONE DOES NOT BELONG. The "in"
items must share a non-obvious property; the odd one out is the player's
target.

## Length budget (mobile UI)
- Question: ≤150 chars (aim ≤100). Stems are naturally short.
- Each answer: ≤45 chars max (aim ≤30). Answer items are usually 1–4 word
  names. If disambiguation is needed (e.g., distinguishing two similarly
  named entities), put the disambiguating context in the question stem,
  not in the answer item.

Examples of stems:
- "Three of these are mammals. Which is not?"
- "Three of these are landlocked countries. Which is not?"
- "Three of these are programming languages named after people. Which is not?"

Distractor rule: the three "in" items should share a property that's
recognizable but not blatantly obvious. Surface-level shared traits (all
green, all start with B) are too easy and produce no insight. The categorical
property should be something a player can verbalize after the reveal.
