/**
 * dsh-slopo — browser half: the bundle's configuration page on the Plugins page.
 *
 * Where the card lives, and why it moved. Up to dsh 0.1.6 the settings surfaces
 * were: a settings namespace a plugin registered for itself, plus a
 * `settings.plugin.item` card the plugin's client half registered under that
 * namespace key, rendered inside Settings → Plugins → Plugin configuration.
 * 0.1.7-rc.2 removed both halves of that contract:
 *
 *   * `ctx.settings.installSection(...)` no longer exists, and a namespace is no
 *     longer chosen by the plugin — it IS the Loader profile entry id, which the
 *     bundle's own patch declares (`dsh-slopo`).
 *   * the `settings.plugin.item` slot and the `settingsScope` service no longer
 *     exist either. Configuration now lives on the Plugins page, and a bundle's
 *     own settings register into `plugins.bundle.config` keyed by the bundle's
 *     PACKAGE NAME, which the page only dispatches for a package it lists.
 *
 * The service that replaced `settingsScope` is `configForms`, and the object it
 * hands out for one entry (`configForms.get(id)`) is API-compatible with what
 * this card used before: `getSnapshot()`, `subscribe()`, `mutate(ops, revision)`.
 * What actually changed is the chrome. The framework now ships the form
 * vocabulary this card hand-rolled — `SettingsFormModel` stages the edits and
 * fences the save with the revision the drafts were read at, `SettingsForm`
 * draws the frame and the single Save, and the field controls carry the
 * overridden badge, the reset and the invalid-edit block. Reproducing that by
 * hand is what the file used to do; using it is the point.
 *
 * Hand-written plain JavaScript inside the module-loader wrapper, with no build
 * step and no bundler. `dsh plugin add git+…` fetches sources rather than build
 * output, so a `prepare` script would make every user allowlist a build before
 * the first install succeeds. The imports are `react` and
 * `@deepseek-ai/dsh-client-ui-primitives`, both platform seed words; anything
 * outside that table would have to be bundled into this file or declared in
 * `dsh.client.external`.
 *
 * Styling is inline on purpose, for the same reason: there is no stylesheet this
 * file may reach.
