Business workspace hub

What changed

A business used to be five sibling routes (edit, playbook, corpus, publishing, content) with no way to move between them except back links. The hub now lives at /app/business/[id]/content and its tabs are routes:

Tab	Route
Edit	/app/business/[id]/content/edit
Playbook	/app/business/[id]/content/playbook
Content	/app/business/[id]/content
Brand Base	/app/business/[id]/content/corpus
Publishing	/app/business/[id]/content/publishing

BusinessWorkspaceTabs.vue (connect layer) renders the bar on every tab page — but not on the board's card drill-in (content/[itemId].vue), which is a drill-in, not a tab.

Why routes, not a client-side tab state

Each tab deep-links and the browser back button works. A parent content.vue + <NuxtPage/> shell would have wrapped the item drill-in in tabs too, so the bar is a component each page renders instead.

Old URLs

edit, playbook, corpus, publishing are now tiny await navigateTo(...) redirect pages, so old bookmarks and links keep working. Internal links were repointed (business card, AddBusinessModal, BusinessInitial, the playbook flow stepper, the media page's dead /app/businesses link).

Creation flow

• The promo checkbox step (StepZero) was removed — pure friction before the user has a business.
• The channels and competitors chosen in the extraction step are now persisted: they live on the modal, not the extracted result, so submitFinalForm merges them into entityDetails. Previously channels was hardcoded [] and competitors were never saved at all.
• The card is now one compact row (initial, name, status, one meta line) with edit/playbook/Google/delete collapsed into an overflow menu.

Gotchas

• Moving a page into content/ changes its relative <i18n src>. edit.vue needs ../../business.json; BusinessPlaybook.vue's #site/.../[id]/playbook.json moved to [id]/content/playbook.json.
• Static tab routes (content/edit.vue) outrank the dynamic content/[itemId].vue — that is what keeps /content/edit from being read as an item id.
• publish.vue stays a route (the composer) and the Publishing tab links to it as "New publication" rather than embedding it.

Verify

1. /app/business/<id>/content shows five tabs; each renders without a nested header.
2. /app/business/<id>/edit redirects to /content/edit.
3. Creating a business with channels/competitors saves them into entity_details.
