Pure `nix fmt` output from the commit before this one — no hand edits. 203 files: 52 md, 42 tsx, 32 js, 32 css, 21 ts, 13 html, 8 json, 3 mjs. Reproduce with `nix develop -c nix fmt` on the parent commit; the result should be byte-identical to this tree. None of the 13 `.prettierignore` entries appears here — verified by intersecting the changed-file list against the ignore file, with a control proving the intersection finds a match when one exists.

// hive-btn.js — <hive-btn>, the button primitive for modal.js's dialog
|
|
// buttons. Autonomous custom element (previously a customized built-in,
|
|
// `<button is="hive-btn">` — dropped: `is=` upgrades can't host a shadow
|
|
// root at all, which crashed every themed dialog, and reads as a hack
|
|
// regardless once you know that). A real `<button>` lives inside the
|
|
// shadow root instead, so native click/keyboard activation and
|
|
// `:disabled` still come for free — just one level down from the host.
|
|
//
|
|
// `delegatesFocus: true` on the shadow root means `.focus()` on the host
|
|
// (what modal.js calls) focuses the inner button directly, and a click
|
|
// anywhere on the host focuses it too, matching native `<button>` feel.
|
|
// The inner button's native `click` is a composed event, so it bubbles
|
|
// out through the shadow boundary — callers add `click` listeners on the
|
|
// `<hive-btn>` host exactly as they would on a plain `<button>`.
|
|
//
|
|
// Usage: `el('hive-btn', { type: 'button', variant: 'danger' }, 'label')`.
|
|
// `variant` ∈ 'cancel' | 'confirm' | 'danger' | unset (neutral default) —
|
|
// reflected straight through to the inner button so hive-btn.css's
|
|
// `:host([variant="…"])` selectors keep working unchanged.
|
|
// `disabled`/`type` are likewise plain attributes on the host, mirrored
|
|
// onto the inner button on connect and on every attribute change.
