The screenshots are the ad

The blocker sounds trivial: the Play Store gauntlet demands tablet screenshots and he doesn’t own a tablet ▸ 6:40. The obvious path, run the Flutter app in a resizable browser, dies on a real lesson: cross-platform isn’t uniformly cross-platform, the audio libraries differ per target, so the web build simply breaks ▸ 7:29. The working answer is an Android emulator, LD Player with ADB debugging enabled, which renders Severo as any device on demand ▸ 9:50, anime-waifu loading ads included ▸ 12:48.

The titular flaw is conceptual, caught while reading the documentation: those screenshots aren’t a paperwork formality, they’re the store listing’s carousel, the thing every potential user swipes before deciding, “es la propaganda, básicamente” ▸ 19:04. Which reframes everything: not random captures but designed frames, stylized yet minimal per the guidelines ▸ 18:31, and then the combinatorics land, phone plus 7-inch plus 10-inch, multiplied by per-language store profiles under manage translations ▸ 20:56. Scope control follows immediately: Spanish, English, Portuguese, nothing else for now ▸ 21:42, and the design lands where the relay says it should: “ahí es donde yo necesito tu ayuda”, Julia ▸ 19:44.

The one bug still standing is a beautiful one: Severo’s system prompt is written in English, so a user who says “quiero aprender inglés” confuses the agent, which reasons that the conversation is already in English and teaches Spanish instead ▸ 22:41, grading the user on Spanish words they obviously know ▸ 25:09. Per-language prompts would multiply unmaintainably, so the fix is pure prompt engineering plus one defensive rule, unknown native languages fall back to English ▸ 26:11. Morale, despite everything: “cada vez me siento más seguro de Severito, ya coge forma” ▸ 22:22. The app is done; the ad for the app is the work now…
