Saga Library of Echoes — at midnight, 12 named books literally whisper to each other and bend their attention toward Imogen Larkspur's 'The Wandering Heart'
A 3D EMERGENT SAGA demo: Brimsworth Public Library after closing. ACT 2 midnight: 12 named books literally whisper to each other (canvas-sprite word-ghosts float up like audio visualizer). ACT 3 ONE MIND twist at minute 5: a 66-pair neural-attention glyph bends every book's whisper toward Imogen Larkspur's 'The Wandering Heart' on shelf 7. Bytes the cat naps on a recipe book through the dawn coda. Like Howl's Moving Castle's library scene meets Neil Gaiman's Sandman library meets Studio Ghibli's whisper-of-the-heart hush.

## What this is
A 3D recreation of Brimsworth Public Library after closing across 3 acts + dawn coda. 25 director cameras cycle every 9-13s (front-doors-closing, librarian-desk-bytes-asleep, shelf-7-imogen-glow, midnight-whisper-pan, ONE-MIND-glyph-overhead, word-ghost-rising, recipe-book-bytes-close, dawn-windows, plus 17 more). 200 named entities: 12 talking books + 8 staff + 80 shelf plates + 40 patron-ghosts (the long-faded readers who keep coming back) + 60 name pool. Each of the 12 books has metadata (author / year / era / theme / shelf / whisper) rendered live in the Book-Brain panel with a NEURAL ATTENTION GLYPHS LIVE indicator. Word-ghost canvas-sprite particles literally float UP from books as the audio visualizer for whispers — when a book is whispering loudest, its word-ghost column is densest.
The story is a 3-act emergent narrative + dawn coda. CLOSING (0-120s): Mira Quill locks the front doors, shelves the day's returns, kisses Bytes the cat goodnight on the recipe book at her desk. MIDNIGHT WHISPERS (120-300s): the 12 books begin whispering to each other — 66-pair NEURAL ATTENTION GLYPH (LineSegments mesh) renders the conversation in real time; Word-ghost particles rise. ONE MIND TWIST (300-420s): at exactly 5 minutes, all 12 books' attention vectors converge — the 66-pair glyph bends visibly toward Imogen Larkspur's "The Wandering Heart" on shelf 7 — "ONE MIND" — every book's whisper joins the same sentence — word-ghosts spiral toward shelf 7 — Bytes opens one eye on the recipe book. DAWN CODA (420-600s): light returns through the high windows, books fall silent, Bytes purrs, Mira Quill returns at 6am, opens the library, and Imogen Larkspur's "The Wandering Heart" is sitting on her desk with no card. Reseed every 10 minutes runs a new midnight with new whispers.
The library *remembers AND broadcasts*. localStorage saves `library_echoes_saga_v1` AND reads/writes SHARED WORLD STATE `megaverse_world_state_v1` (rainy weather = more word-ghosts; writes "Library of Echoes whispers"). LIVE NEWS TICKER pushes 3 beats per cycle (closing / midnight whispers / ONE MIND glyph). Crossover chyron reads `megaverse_world_state_v1`, `multilayer_books_v1`, `cinema_of_fate_v1`, `whatifs_museum_v1`, `recurring_cast_v1`.
You don't play it. You watch 12 books literally whisper to each other and become ONE MIND at minute 5.
## Why this is mind-blowing
The chyron is the secret weapon: "Wednesday, 11:47pm. Mira Quill locked the doors at 9:00pm. Bytes is asleep on the recipe book. The Pemberton history (1972) starts whispering to the Halloran case files (1908). The bird-watcher's diary (1924) joins. By 11:54pm all 12 books are speaking the same sentence. The 66-pair attention glyph bends visibly toward shelf 7. 'The Wandering Heart' by Imogen Larkspur is glowing. Bytes opens one eye. At 6am Mira returns and finds the book on her desk with no card." That single line stitches three named cast and 12 books in one beat — Imogen Larkspur (long deceased, recurring R20 spaceship-bridge as the actual lineage origin) on the shelf-7-imogen-glow camera with a soft golden halo around the spine of "The Wandering Heart" (recurring cast larkspur +1, attention glyph from all 11 other books to this one max-opacity, news ticker push: "Library of Echoes whispers — ONE MIND at shelf 7"), Mira Quill on the librarian-desk-bytes-asleep camera with her cardigan over the back of the chair and her hand still warm on the recipe book where Bytes sleeps (recurring cast quill +1 NEW, plan tree branch "close library" complete, news ticker push: "Mira Quill closes the library at 9pm"), and Bytes the cat on the recipe-book-bytes-close camera with one eye open at exactly 11:54pm and the other still firmly shut (recurring cast bytes +1, news ticker push: "Bytes the cat hears the books"). The 66-pair NEURAL ATTENTION GLYPH is the structural genius: 12 books × 11 partners ÷ 2 = 66 pairs, each rendered as a LineSegments line whose opacity = attention weight, and at the 5-min twist all 66 lines bend visibly toward shelf 7 in a single second — the most legible "the demo is alive and computing" moment in the megaverse so far. Multiply that by 200 named entities each with brain panels, 12 books with full author/year/era/theme/shelf/whisper metadata, an agentic plan tree for the head librarian, NEURAL ATTENTION GLYPHS as 66 line segments that bend in real time, SHARED WORLD STATE syncing rainy weather to word-ghost density, a LIVE NEWS TICKER, an explicit 3-act narrative + dawn coda, and a "ONE MIND" twist that bends every line in the room toward a single 1924 poetry collection, and you've got a Howl's-Moving-Castle-meets-Sandman library that genuinely earns its emergent-saga scope. NO HORROR. ALL FICTIONAL.
Prompt
Build a single-file HTML page that recreates "Brimsworth Public Library after closing where 12 named books literally whisper across 3 acts + dawn coda" as a continuous 3D autoplay world with AGENTIC PLAN TREES + NEURAL ATTENTION GLYPHS + SHARED WORLD STATE + LIVE NEWS TICKER.
CONCEPT: BRIMSWORTH LIBRARY OF ECHOES — Howl's Moving Castle library + Neil Gaiman's Sandman library + Studio Ghibli whisper hush. NO HORROR.
Hard constraints:
- One HTML file, < 200KB.
- three.js r0.160.0 from unpkg, IIFE strict, reseed every ~10 min.

All R16+R17+R18+R19 spec retained. R20 NEW:
1. AGENTIC PLAN TREE PANEL — Mira Quill (close library / shelve / read / dream)
2. NEURAL ATTENTION GLYPHS — 66-pair LineSegments mesh between 12 books, bends to shelf 7 at twist
3. SHARED WORLD STATE — library reads weather (rainy = more word-ghosts), writes 'Library of Echoes whispers'
4. LIVE NEWS TICKER — 3 beats per cycle
5. 3-ACT NARRATIVE + DAWN CODA — closing / midnight whispers / ONE MIND / dawn
6. 25 director cameras
