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.

// WarnBanner.tsx — <WarnBanner>, the Preact-component successor to the
// shadow-DOM <hive-warn> custom element (../hive-warn/hive-warn.js).
// Same three-tier visual language (mara, on `hive-warn`'s own review:
// "there should be distinction between info, warning, error — all
// warnings should be styled identically") — built as a plain Preact
// component instead so it composes cleanly wherever this package's other
// shared components do (JobqRollup, JobqGraph, ApiErrorPanel), rather
// than needing a shadow root + CSS-as-text build step that only resolves
// under one of the two consuming packages' esbuild configs. `ApiErrorPanel`
// is the first consumer — compose from this instead of duplicating the
// banner's own border/colour/pulse rules locally.
//
// `level` defaults to 'warning', matching `hive-warn.js`'s own default.
// Only `error` pulses — an active incident, not a standing caveat, same
// rule `hive-warn.css`'s own comment states.
import type { ComponentChildren } from "preact";
import "./WarnBanner.css";
export type WarnLevel = "info" | "warning" | "error";
export interface WarnBannerProps {
level?: WarnLevel;
// Passed straight through to the root element's `class` list —
// for a caller-specific concern the banner itself has no opinion on
// (e.g. `ApiErrorPanel` adding a top margin for the context it usually
// sits in), not for re-styling the banner's own look.
class?: string;
children?: ComponentChildren;
}
export function WarnBanner({
level = "warning",
class: extraClass,

}: WarnBannerProps) {
const classes = ["warn-banner", `warn-banner-${level}`, extraClass]
