Century 1924 Founding — Decade 1: Henry Senior Senior Bramble marries Mabel Vellum-original under a flower arch on the village green; Mr. Pemberton I cuts the ribbon on the bakery; the chyron writes 100 years from now her great-granddaughter Lily will walk this same aisle

A 3D BRIMSWORTH CENTURY demo: Decade 1 of 12. Sepia-golden 1924 morning on the village green. Henry Senior Senior Bramble (24) marries Mabel Vellum-original (22) under a flower arch on the same village green where, 100 years later, his great-granddaughter Lily will marry Tomas Field. Mr. Pemberton I cuts the ribbon on the founding day of Pemberton Bakery. The brimsworth_century_v1 ledger is bootstrapped — Year 1924, Decade 1, Generation 1. The same 4-note C-E-G-C wedding leitmotif from R21 plays in 1924 ragtime piano + tuba bass voicing — the FIRST seed in an 11-decade music tree. Like Pixar UP opening montage 1908 + cozy English country founding wedding + Studio Ghibli sepia photograph.

## What this is A 3D recreation of Decade 1 of 12 of the BRIMSWORTH CENTURY arc. THIS IS THE OPENING DEMO OF ROUND 23. Sepia-golden 1924 morning on the village green where, 100 years later, his great-granddaughter Lily will marry Tomas Field on this same green. 36 director cameras cycle through village-green-archway, sepia-walk-in, ribbon-cutting, bakery-founding-7s, 100-year-future-mirror, recurring-bramble-7s, recurring-pemberton-7s, drama-ladder rungs, plus 31 more. 266+ named entities including 6 named ancestors (Henry Senior Senior 24 + Mabel Vellum-original 22 + Mr Pemberton I 44 + Reverend Hollis + Mrs Vellum-the-elder + Mr Vellum-the-elder) plus 260 procedural villagers across 16 surnames × 30 given names = 480 named permutations available. The story is a 3-act emergent narrative. VILLAGE GATHERS (0-180s): the village green dressed with bunting; the founders gather under the flower arch. VOWS BEGIN (180-300s): Reverend Hollis officiates; Mr. Pemberton I cuts the bakery ribbon; the village erupts. THE 100-YEAR FUTURE (300-420s): mid-cycle twist at 5min — chyron writes "100 years from now her great-granddaughter Lily will walk this same aisle"; the 1924 ragtime piano + tuba leitmotif plays the FIRST 4 notes of a C-E-G-C phrase that will evolve through 11 more decades; brimsworth_century_v1.year:1924 is written. The village *remembers AND broadcasts*. localStorage saves `century_1924_v1` AND BOOTSTRAPS the canonical `brimsworth_century_v1` { year:1924, decade:1, generation:'founding', family_tree_alive:[6 ancestors], events:['Founding Wedding 1924','Mr Pemberton I cuts bakery ribbon','100-year future-mirror to R21+R22'] } — every R23 demo reads/increments this. PiP CROSSCUT rotates sepia walk-in / bakery ribbon / photo portrait / live 1924. You don't play it. You watch a great-grandfather cut a bakery ribbon that, 100 years later, his great-granddaughter will run on Saturdays. ## Why this is mind-blowing The chyron is the secret weapon: "1924 · Mabel walks the aisle · 100 years from now her great-granddaughter Lily walks this same aisle · brimsworth_century_v1.year:1924 written". That single line stitches a 100-year arc into a sepia 1924 morning — Henry Senior Senior on the recurring-bramble-7s camera, Mabel on the sepia-walk-in camera, Mr. Pemberton I on the ribbon-cutting camera. The brimsworth_century_v1 BOOTSTRAP is the structural genius: this single localStorage write seeds an 11-demo state machine where Year 1924 becomes Year 1934 becomes Year 1944... and every future R23 demo's chyron reads `brimsworth_century_v1.year` to render the year-stamp. This is not a story about a founding wedding — this is a founding wedding that is the foundation of a 110-year five-generation simulation. ALL FICTIONAL.
