docs(P46): render Marp decks to HTML + PPTX, update README for rendered artifacts

Commit self-contained HTML renderings of both Marp presentation decks to
docs/presentations/ so they are viewable in any browser and on the git
forge. The HTML files embed all images as base64 data URIs and render
the full S&P Global Energy brand theme (#D6002A red-core, #1B1B1B grey-90,
Akkurat Pro font).

Updated the README to document the 3-step process with HTML as a
committed artifact (re-render when Marp source changes) and PPTX as a
Gitea release attachment (binary, not committed to git).

PPTX files are rendered and uploaded to the Gitea release as downloadable
attachments for stakeholders.

+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
+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) with conventions, build commands, and maturity

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

.ciagent/ROADMAP.md

@@ -11,6 +11,8 @@
 - **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`.
