- image_reveal display: larger, object-contain (whole image up to 58vh), no crop
- image prompt optional in back-office (defaults to "Qui est-ce ?"), overridable
- mixed mode reworked: select "Mixte" then toggle sub-modes (Quiz/Images/
Blindtest). Blindtest sub-mode locked under 3 players; mixed itself no longer
needs 3. Server quiz pool formats derived from gameType + mixedModes.
shared: MixMode + RoomSettings.mixedModes (default quiz+image).
- DB: prompt uniqueness is now a partial index (excludes image_reveal) + unique
index on image_url; lets many images share the generic prompt, dedup by URL.
- seed: db:seed:images pulls Pokémon (PokéAPI) as image_reveal questions with
official artwork (remote URL) + FR/EN accepted answers; idempotent by image_url.
Verified: migration applied, Pokémon seed inserts FR+EN, image mode serves only
image_reveal, all checks green (23 tests).
