/**

* Browser tab title composition. Mirrors the Go rule in
|
|
* `apps/backend/internal/webapp/shell.go` (`ComposeTitle`): the shell rewrites
|
|
* `<title>` server-side so the prefixed title is correct from first paint, and
|
|
* this covers the `/api/v1/app-state` boot path, which never renders through
|
|
* the shell.
|
|
*
|
|
* "Kandev" is the product name, not translatable copy, so no `t()` is involved
|
|
* — consistent with the static `<title>` in `index.html`.
