Brimsworth Generations — Generation 4/12: Year 2140, Jules Vellum-Wren composes a symphony for Brimsworth's tricentennial (Vellum-Wren surname mutation, tricentennial symphony premiere, R27 leitmotif voiced in solo bassoon)
A 3D BRIMSWORTH GENERATIONS demo: Generation 4 of 12 (2140). The R21 wedding cast's descendants 4 generations forward. Jules Vellum-Wren composes a symphony for Brimsworth's tricentennial. Surname has mutated to Vellum-Wren through 4 generations of marriage. Signature object passes down: 4-generations-old brass goggle (heirloom from R24) joins this generation's milestone artifact (tricentennial symphony score). Same R21 wedding-day C-E-G-C leitmotif from R23/R27 voiced in solo bassoon — the fourth of 12 generational voicings. Genealogical-inheritance HUD shows full family tree. brimsworth_generations_v1 ledger appends. BroadcastChannel('brimsworth_generations') emits family-tree updates. ALL R16-R27 retained (cameras, day-cycle, multiverse-portal cat-meet, R27 audio-sync). ALL FICTIONAL — a hopeful imagined future.
Build a single-file HTML page that recreates "Generation 4 of 12: Year 2140, Jules Vellum-Wren composes a symphony for Brimsworth's tricentennial" as a continuous 3D autoplay world.

What I learned shipping it
- How to model genealogical inheritance across 4 generations with a brimsworth_generations_v1 localStorage ledger that appends each generation's metadata (gen_id, year, surname, parents, signature_object, eye_color, leitmotif_voicing, milestone) and cross-reads from R22-R27 canonical keys
- How to render a 4-deep family tree HUD on the right edge of the canvas showing the chain of mutations from R21 Lily Bramble + Tomas Field down to year 2140's Vellum-Wren line
- How to inherit and voice the same R21 4-note C-E-G-C wedding leitmotif in solo bassoon (R27 Movement IV Largo) as one of 12 generational voicings, building Web Audio API synthesis with ADSR envelope and broadcasting tempo state across browser tabs via BroadcastChannel('brimsworth_generations')
