# Prototypes

Frozen design history. Every file here is a snapshot of what a design looked
like on the date in its name, kept so the evolution is walkable. Nothing here
is maintained, and nothing here is loaded by anything that runs.

Most pages are self-contained: open one and it renders.

## The world face

The world wallpaper's engine used to live here and was hand-copied into
`~/.dotfiles/settings/faces/` on every change. Both copies were byte-identical
and both test suites ran the same tests, so the duplication bought nothing and
risked drift — the two pages' palettes had already diverged enough to break a
scripted edit.

The live engine, its tests and the lab page now live only with the shipped
face, in the dotfiles `settings/faces/` directory:

- `timeline-face-engine.js`, `timeline-face-spine.js` — the engine
- `world.html` — the projected wallpaper
- `lab.html` — the same engine with a movable home and a fast clock, for
  trying an idea without touching the wallpaper

`make test-faces` in dotfiles runs their tests.

`2026-07-31-timeline-face-prototype-6.html` and the option-A pages load the
engine, so they are readable here but not runnable here. The engine is
deliberately **not** kept in this repo: it carries a list of the places I
travel to, with coordinates, and this repo is published. A design record is
not worth publishing that.

To run prototype 6, copy the two engine modules in beside it:

```sh
cp ~/.dotfiles/settings/faces/timeline-face-*.js docs/prototypes/
```

They are gitignored here, so a copy stays local. Note that the live engine
keeps moving: prototype 6 is a photograph of one day's design and a current
engine may not render it the way it looked.
