atlas 39b95c2ede treefmt: apply prettier
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-tab-strip.js — <hive-tab-strip>, the markup-owning tab-strip custom
// element behind the logs/credentials/core/builds sub-page tabbars. Owns
// rendering the <a class="hive-tab"> markup from a declarative `tabs` list
// instead of every page hand-writing the same <nav><a>...</a></nav>
// boilerplate, then wires the existing createTabStrip() behaviour
// (@hive/shared/tabs.js) over what it just rendered — no behaviour
// duplication, this is markup only.
//
// Light-DOM (no shadow root): the existing .hive-tabbar/.hive-tab/
// .tab-count CSS (tabs.css + dashboard.css) already targets plain classes
// on the tabbar/tab elements directly, and tab *panes* stay page-owned
// content this element never touches — no slotting/scoping need the way
// <hive-menu>/<hive-side-panel> have.
//
// Host keeps its own id/class/role (same as the <nav> it replaces, so
// existing CSS selectors + #id lookups keep matching); pass a `prefix`
// attribute (e.g. `prefix="logs"`). `configure({ tabs, defaultId, onShow })`
// then renders one <a> per tab —
// <a class="hive-tab" id="${prefix}-tab-${id}" href="#${id}" role="tab"
// aria-controls="${prefix}-pane-${id}" data-tab="${id}">${label}</a>
// — same id/aria-controls scheme the hand-written markup used, so each
// page's panes (aria-labelledby="${prefix}-tab-${id}") don't need to
// change. A `badgeId` tab also gets a nested `<span class="tab-count"
// id="${badgeId}" hidden>` (matches builds.html's rebuild-queue count
// pill), then wires up createTabStrip() and returns exactly what it
// returns ({ show, active }) — every existing `.active()`/`.show(id)`
// call site keeps working unchanged. Call configure() exactly once per
// element (throws if called twice), mirroring the old call sites.
