Head Case · design prototype · 2026-07-27

One front door,
a thousand worlds.

Three comparable directions on identical page anatomy — fandom-finder routing, worlds gates, brand-led pages, design-first discovery, a Design Hub that only ever resolves valid variants, and Tech-Pack set building with stated reasons — plus Fable K3, the picked merge of the Kimi prototype's home and PDP structure onto the same spine. The licence leads; Head Case is the platform underneath.

02 · Signal

03 · Chameleon

04 · Fable K3

The chosen merge (Cem, 2026-08-07), built by Fable: the Kimi K3 prototype's Casetify-school anatomy — mosaic home, circular product rail, configurator PDP with reasoned add-ons — recoloured Head Case yellow, with the Chameleon costume-change per world. Standalone at headcase-fable-k3.netlify.app.
