[B2B Feature]: Author an account microsite from an approved template via the assistant

[anfibiacreativa]

Describe the problem

A seller needs an account-specific microsite quickly, but authoring one by hand from scratch is slow and inconsistent. There is no assistant-driven path that turns a short brief plus the customer's report data into a ready page.

Propose a solution

Add a skill that, given a natural-language brief (and optionally an existing report as a seed), selects an approved template, composes the microsite page from reusable report blocks, personalizes copy/branding for the account, and creates the page under the account's folder — with the seller approving the write.

Flow

1. Seller describes the account / pastes a brief (optionally points at an existing report).
2. Skill picks an approved template and assembles the page from report blocks.
3. Skill personalizes headings, branding, and data for the account.
4. Skill creates the page (seller approves the content write).
5. Page is available to preview/publish.

Associated skill

New microsite-builder skill (name TBD) in the skills project.

Affected blocks / pages

Report template blocks (e.g. report-hero, report-stats, report-chart, report-download); new page under the account folder.

Analytics data involved

The customer's report/analytics data used to seed the page (metrics, insight sections).

Priority

Would improve day-to-day
