Serves `index.html`/`app.js` (via `staticHTTPServer`) and the `POST /api/generate` AI Horde image backend. |\n| `index.html` | The app UI. |\n| `app.js` | All client logic — story writing, **strict scripting engine**, image/voice/video compilation. |\n\n## The Strict Scripting Engine\n\nInstead of recapping real manhwa pages, the tool writes an **original story from a premise** and enforces a hard line-level style:\n\n- **Present tense, active voice**\n- **8–12 words per line**\n- **One action per sentence**\n- **No filler or meta-commentary**\n\nHow it's enforced in `app.js`:\n\n- `validateLine(line)` — heuristic validator that returns `{ ok, words, issues[] }`. It **flags** violations (past-tense verbs, passive `…by…`, chained actions, filler phrases) rather than silently rewriting text, since programmatic grammar conversion is unreliable.\n- `renderValidation(lines)` — paints each line in the storyboard green/red with its word count and the exact issue, plus a summary note.\n- `writeStory` — after an LLM call, if **more than ~30% of lines fail** validation, it **retries the LLM up to 2×**, feeding back the precise list of failing lines (\"Line 2 (14w): 14 words…\") so the model corrects itself. One or fewer bad lines is tolerated.\n- `defaultStory()` — the no-key offline fallback. **Fixed bug**: the original returned a hard-coded 5 lines regardless of the panel count, so narration repeated verbatim. It now builds exactly `count` distinct lines via combinatorial slot-filling (`NARR_OPEN` × `NARR_WHERE` × `NARR_THREAT`), validated in place, so 12 panels never repeat.\n\n## Keys\n\nAll keyed services are optional (click **🔑 Keys** in the app and save → stored in your browser's `localStorage`):\n\n- **LLM Key** — any OpenAI-compatible endpoint (`sk-…` from OpenAI/OpenRouter/Groq) for AI story writing.\n- **AI Horde Key** — server-side secret for images. Optional (anonymous works, with lower queue priority). Set the val's `AI_HORDE_KEY` env var.\n- **Murf AI Key** — paid TTS; leave blank to use the free TTS proxy (`tts-proxy`).\n\n## Image backend\n\n`main.ts` generates one image per panel on [AI Horde](https://aihorde.net) as same-origin data URLs (so the canvas is never tainted), polling until done with a 2‑min/panel cap. Every panel shows a canvas placeholder instantly, then real art swaps in as each URL resolves.\n\nNotes on the AI Horde integration (these were the bugs that blocked image generation):\n\n- **Dimensions must be multiples of 64** — the backend snaps them.\n- **An `apikey` header is required on every request** — it defaults to the shared anonymous key `0000000000`.\n- **Anonymous is capped at 850×850** — the backend scales the requested size down to fit while preserving aspect ratio. Setting a registered `AI_HORDE_KEY` lifts the cap to 2048 (full 720p/1080p quality).\n",[100],{"_35":99,"_13":100,"_64":101,"_66":-5,"_67":68,"_69":87,"_70":71,"_37":119,"_17":33,"_74":24,"_76":103,"_78":50,"_79":-5,"_110":120,"_18":121},{"_35":90,"_13":91,"_64":92,"_66":-5,"_67":68,"_69":93,"_70":71,"_37":116,"_17":95,"_74":96,"_76":97,"_78":50,"_79":-5,"_110":117,"_18":118},{"_35":82,"_13":83,"_64":84,"_66":-5,"_67":68,"_69":85,"_70":71,"_37":113,"_17":87,"_74":24,"_76":88,"_78":50,"_79":-5,"_110":114,"_18":115},{"_35":62,"_13":63,"_64":65,"_66":-5,"_67":68,"_69":31,"_70":71,"_37":109,"_17":73,"_74":75,"_76":77,"_78":50,"_79":80,"_110":111,"_18":112},["D",1787075167558],"children",[],[63],["D",1787071823332],[],[83],["D",1787075174402],[],[91],["D",1787071796347],[],[100],"22105ad8-254f-4b2b-bf0e-07393d6a9260",["D",1787071796347],"legacyEnvVars","httpPrivacy","description","AI
