- The Build: the homepage. A scrollybook told by the machine that made the album: the overload, the sound, the seams, the website, the vault, the live show, the visuals, the rig, the instruments, the crew and the package. It has its own phone and tablet editions.
- ARCHIVE_404: the album page. The matrix-rain boot intro, the CHROME hero with the manifesto line under the logo, BEYOND THE RECORD and SIGNAL (booking).
- Catalogue and Collective: the songs and the crew, each on a page of its own.
- Visuals: the visualiser series as one channel, one engine per chapter (PHOSPHOR, DATAMOSH, BEAT CUT, CHROME), drawn live at the dock's playhead.
- 402_REQUIRED: the second record's page, built like the album's, with its own visuals (SORT, MOSH, HARVEST). The two records link to each other everywhere.
- Rig, Live and Vault: behind the access key, each holding both records (a switch on the rig and the vault,
?r=402on the live show). The repo is public, so everything private ships encrypted (AES-256-GCM, key from the access key) and the big files come from a private repo through short-lived signed links. - One player dock follows you across every page: the record's tracks in album order (20 or 15), lock-screen controls, and it resumes where you left off.
