What shipped Zen Old Mincho, IBM Plex Sans JP and Zen Kaku Gothic New

Takes

Four takes on one idea: the edge of what a student knows.

All four say the same thing and none of them say it the same way. Point at any of them to see it in full colour.

Build

What is actually in it.

Type
Three Japanese faces held on one baseline: Zen Old Mincho, IBM Plex Sans JP and Zen Kaku Gothic New, on a fluid clamp() scale
Structure
A ten-section landing page plus four subpages. Hand-written HTML and CSS, no framework
Signature
A sticky scroll-driven sequence, "ONE DAY ON THE PLATFORM · 一日", whose sections are generated in JavaScript
Motion
Canvas 2D, a marquee, backdrop-filter, and a click-to-enter intro gate
Accessibility
prefers-reduced-motion handled
Language
Japanese and English throughout, not a translation layer bolted on
Unwritten, on purpose

The brief, why the score-report direction won, and what happened after launch are Jesy's to write. Every line above was read off the built site or its source. Note also that the four subpages are thin and the site carries no og:url, both of which are still open.
