/* ─────────────────────────────────────────────────────── the sync pill
 *
 * syncpill.js sets the text and exactly one `is-*` class; every rule below is
 * driven by that class and nothing else. It writes no inline style, because the
 * CSP has no 'unsafe-inline' — so if these rules are missing, the pill still
 * says the right words, unstyled, rather than disappearing.
 *
 * The states are ranked by how much they should interrupt: `synced` is almost
 * invisible, `n pending` and `update available` are worth a glance, and the
 * three that mean "your writing is not leaving this device" are red.
