H3 Prompt Studio 1.3.1 — Text-only Game startup

Fixes a text-only Game opening failing with a misleading missing-model error when ComfyUI was offline.

• Extra reference images now require explicit opt-in. Ordinary Game actions use text and existing references directly.
• Offline or unreadable ComfyUI inventories are distinguished from verified missing model components. Available alternatives never silently change the selected generator.
• Game settings include generator refresh, specific availability diagnostics, and visible saved selections.
• Legacy automatic optional-image failures can be resumed only when the saved job proves it failed before submission. Existing assistant and job evidence is retained; submitted or uncertain work is never silently discarded.

The actual reported failed turn was recovered in the installed app with no extra image job. Its 608 × 320, 3.042-second clip played in the browser and the game returned to the next-move state. This verifies the reported startup path, not every possible game action or visual outcome. The earlier scene-continuity validation report now explicitly records the missed case.

The release ZIP contains application source and the built frontend; private stories, credentials and model files are excluded. The existing v1.3.0 demonstration videos remain available in that release.

For an existing installation, preserve its data folder when updating application files. Start the configured LM Studio and ComfyUI servers, then reload the app. An image generator is optional for normal Game play; H3 video still requires ComfyUI running.
