v9.19.0 — Admin /admin/account self-account page

v9.19.0 — Admin "My account" page (/admin/account)

The admin chrome had no place for an admin to manage their own account — <AdminProfileMenu>'s "My profile" item linked to the storefront /account page, bouncing the admin out of the panel. There is now a dedicated /admin/account page, rendered inside the admin shell, where the signed-in admin can edit their display name + phone, upload/remove their profile photo, and change their password (email stays read-only). It reuses the existing ProfilePhotoCard / ProfileCard / ChangePasswordCard components, so there is no new form or data logic.

<AdminProfileMenu>'s profileHref default changes from /account to /admin/account so "My profile" lands on the new in-chrome page. <AdminRoot> dispatches /admin/account automatically, so consumers using the default admin route tree get the page for free.

Ported from the standalone luivante store.

No consumer action required

Additive — a new admin page wired through the existing <AdminRoot> dispatcher. The only behavior change is <AdminProfileMenu>'s "My profile" default destination (/account → /admin/account); pass profileHref="/account" to restore the old target if you relied on it.

Added

• src/admin/admin-account-page.tsx — the /admin/account page; stacks the three account cards under a page header. Exported from src/admin/index.ts.

Changed

• src/admin/admin-root.tsx — case 'account' dispatches <AdminAccountPage />.
• src/admin/admin-profile-menu.tsx — profileHref default /account → /admin/account.
