Мастерская переехала на eureka2: страница /workshop — часть сайта (lib/workshop.js, общая шапка/навигация/подвал), оформление в tokens сайта (assets/workshop/ workshop.css), компоненты читают данные пода по SSE /workshop/sse. Компоненты перенесены на сторону сайта, геометрия мозга — assets/workshop/. build.js собирает страницу (active: workshop).

/* <workshop-target> — where the fly is heading right now.
|
|
*
|
|
* The flight reports a `target` event on every step (throttled server-side to a
|
|
* sane rate), naming the word it currently pulls toward. That word changes
|
|
* fast — several per second — and this element shows it as a running line, with
|
|
* a short trail of the words it passed on the way. This is the fly *flying*,
|
|
* not the fly eating: the meal stream (workshop-words) stays separate and still
|
|
* arrives ~once every ten seconds.
|
|
*
|
|
* A `target` with `none: true` means every word was on cooldown — there is no
|
|
* destination at that moment, and the element says so instead of freezing on a
|
|
* stale word.
|
|
*
|
|
* Honesty: the fly does not "want" or "aim" — "target" is our layer over the
|
|
* brain's state. Which word wins is measured (`sim`); the hungriness shown is
|
|
* the author's frame, labelled on the page.
