docs(P45): S&P Global Energy theme + title/footer/subtitle updates for Marp decks

Apply S&P Global Energy brand theme to both Marp presentation decks:

1. Title headers: 'Agentic Cloud Delivery Platform — How The Platform Works'
   and 'Agentic Cloud Delivery Platform — The Developer Experience'
2. Footer: 'Confidential · For Senior Leadership' → 'Internal'
3. Title slide subtitle: removed 'Senior Leadership Briefing' (clean title)
4. S&P Global brand theme (colors extracted from live spglobal.com CSS):
   - H1/H2: #D6002A (S&P red-core, confirmed from logo SVG + compiled CSS)
   - Title slide bg: #1B1B1B (S&P grey-90) with 8px #D6002A top accent bar
   - Body text: #1B1B1B (grey-90)
   - Blockquote border: #D6002A, text: #2E2E2E (grey-80)
   - Table headers: #F0F0F0 (grey-5)
   - Font: 'Akkurat Pro' (S&P corporate typeface) with web-safe fallbacks
   - theme: default kept as Marp base (simple)
5. Last DX slide: 'The Outcome for Leadership' → 'The Desired Outcomes'

+Docs-only NFR patch on the v1.9 line. Two leadership-facing presentation

+leadership (CTO, Head of Cloud, Head of Infrastructure, Head of DevOps).
+Each deck has a full markdown source of truth (with speaker notes + mermaid

+synthesis → PPTX export) with conventions, build commands, and maturity

 ## Requirements
 
 ### v1.0 (Prior milestone — the demo)

.ciagent/ROADMAP.md

@@ -11,6 +11,7 @@
 - **v1.6 (complete, tag `v1.6.0`):** consumer-facing docs restructure + terminology normalization + environments concept. `docs/` becomes a Jekyll-style GitHub Pages site. `acdl_platform/` is renamed to `core/`. L2 → "modules", L1 → "primitives", "composition" → "pattern" in prose. README restructured: Features + Roadmap (no internal status), repository roles restated (consumer = app code + contracts + CI definitions), mermaid fixed (visible text, security-checks + infrastructure-apply stages, no tool names), credentials section minus go-gitea/waivers. Platform-managed environments concept + a minimal onboarding scaffold. `.ciagent/` + `.gitea/` references removed from all consumer-facing docs.
 - **v1.7 (complete, tag `v1.7.0`):** production platform + contract ingestion + pipeline maturation. Rename `static-assets` → `static-assets` (D-048 — incl. `.ciagent/` historical narrative). Author `cloudfront` + `waf` primitives; augment `static-assets` to a production-ready S3 + CloudFront (OAC) + WAF stack (D-049). Tagging-standard enforcement (Checkov custom rule, D-043 closure, D-054). Wiz adapter stub (D-052) + Kyverno K8s-native adapter (D-053). Platform Lambda + DynamoDB `acdl-contracts` table for contract ingestion (D-051) + cross-account IAM. Deploy outputs via SSM SecureString + GitHub PR comment (D-050). Uniform error reporting via the Lambda `report_error` action → GitHub issue on the platform repo (D-055); Gitea excluded. Stage comments after every successful pipeline stage. Three platform pipelines (platform-test unit+integration, primitives-plan, patterns-plan). Release job with semver + MAJOR.MINOR/MAJOR tag maintenance (D-057). `uses:`/`ref:` bumped to `@v1.6`; floating `v1.6` + `v1` tags created in Phase 22. Remove the legacy consumer-repos directory (a v1.2 artifact, removed in v1.7); add validated per-module examples (`modules/<name>/examples/`, D-058) including a new RDS primitive demonstrating multi-engine variation (D-059).
 - **v1.8 (complete, tag `v1.8.0`):** P1 remediation + uptime monitoring + engineering standards + encryption/deletion-protection by default + decommission alias + path documentation. Clears 8 pending P1 issues (P1-3..P1-9 + S1). Adds per-stack CMK + encryption-by-default for all primitives. Adds deletion-protection-by-default + L2 feature flag. Adds uptime-kuma primitive (ECS Fargate, deployed by default after L2, separate state, feature flag, alert channels). Adds decommission mode (2-step pipeline with HITL SRE gates + CMDB-validated change request). Adds `modules/STANDARDS.md` (L1+L2 authoring + review standards). Adds `schemas/README.md`, `pipelines/README.md`, `adapters/README.md`.
+- **v1.9.1 (complete, tag `v1.9.1`):** leadership presentation decks. Two leadership-facing presentation decks (How the Platform Works + The Developer Experience) for senior leadership (CTO, Head of Cloud, Head of Infrastructure, Head of DevOps). Each deck has a full markdown source of truth (with speaker notes + mermaid diagrams) and a lean Marp deck (no speaker notes, embedded PNG diagrams). A README documents the 3-step slide creation process (full markdown → Marp synthesis → PPTX export). Docs-only NFR patch.
