The system blueprint
Every module earns its place in the workflow.
These are separate products because each solves a distinct job. They belong together because the next engineering decision begins where the previous one stops.

Boundaries that travel with the kit
Useful because the limits are visible.
- External tools, accounts, infrastructure, and usage costs are separate
- The bundle does not provision accounts or deploy production changes automatically
- Member major-version upgrades are not included unless explicitly added
Each included package carries its own upstream attribution and license notice.

What is included?
Six complete installable skill packages, their documentation, member evidence, and legal notices in one versioned ZIP.
Does it provide Stripe, database, or hosting accounts?
No. It provides reviewable workflows for compatible tools and services you already have access to; accounts and usage costs remain separate.
Can I buy the skills individually?
Yes. The bundle is priced below the regular combined value and below the total of the current individual prices.
