0.3 Three routes

Pick one as your spine; the others become skim-and-return.

   ROUTE A -- CLOUD / PLATFORM SECURITY  (~10-12 weeks)
     Parts 2, 3, 4, then 8 (detection for cloud), then Part 10 projects 1 & 4.
     Part 5 (distributed authz) as needed. You end able to own security for a
     cloud-native platform.

   ROUTE B -- APPLICATION / PRODUCT SECURITY  (~8-10 weeks)
     Parts 6, 5, 7, then Part 1, then Part 9 (SSDLC, vuln mgmt, offensive
     program). Projects 2, 3, 5. You end able to run product security for an
     engineering org.

   ROUTE C -- DETECTION & RESPONSE  (~8-10 weeks)
     Parts 1, 8, then 2 & 4 (you must know cloud/k8s to detect attacks on
     them), then 9 (metrics, program). Projects 1 & 4. You end able to build
     and run detection engineering.

   FULL PASS  -- ~6 months part-time, in order. Recommended if security is
     now your primary role.
