The plugin list, grouped by what a plugin actually is

Category has been in the plugin contract since it was written — apis-external,
drives-external, drives-local — and every builtin declared the same one, so it
grouped nothing. Two of the three talk to a wallbox and one talks to a car
manufacturer, and those are different questions an operator arrives with: the
Toyota card is where a driver's account gets linked, the Anker and Greencell
cards are where a charger's broker and credentials live. So vehicles and
chargers join the constants and the three builtins say which they are.

The panel groups on that field rather than on a list of names, which is what
keeps an external plugin from needing panel code. Tab order mirrors the
constants; a category with nothing in it gets no tab, and a single group hides
the bar entirely, so an install with one connector looks exactly as it did.
A category the panel does not recognise — or an empty one — falls to the
external-APIs tab rather than vanishing, because a plugin nobody can see is a
plugin nobody can disable. The selected tab falls back to the first group when
its own goes away, which is what removing the last external plugin does.

Registration still asks only for name, base URL and provider, so a plugin
registered at runtime lands under Other APIs until its manifest names a
category. That path already works and is the honest default: the panel is
guessing about a service it has never spoken to, and the service can say.

The header lockup is the other half. It was a copy of the Web App's mark rather
than the same mark, and copies drift — a 32px icon against 28, a 24px wordmark
against 21.6, "Driver" at text-strong instead of white, "Vault" a step lighter
than brand-400. The Web App's Logo.vue moves in verbatim, props included. The
one thing it cannot inherit is which variant to render: the Web App's rail is
always dark, while this panel flips with its own theme toggle, so on-dark is
bound to the theme and the hand-rolled bar fills that existed to survive that
flip are gone.
