Changes

• Standardize the concise README with HTML/PDF links, canonical contact links, current presenter title, all existing resource URLs, and MIT license.
• Preserve the six-demo catalog and setup/teardown links in the existing linked cluster guide. Samples, demonstrations, themes, and talk body are unchanged.
• Repository-wide Senior/Sr sweep found no outdated presenter titles; cover/bio already use Principal Software Engineer. Replace the active footer's old Twitter handle with linked Blog/Bluesky, preserving the intentionally struck-through historical Twitter reference and closing contacts/resources.
• Add build/Slides.pdf publishing alongside HTML/assets and pin both Marp renders from floating latest to locally verified v4.5.0. Existing Pages actions were already current; triggers, permissions, concurrency, and asset copying are unchanged.

Verification

• Marp 4.5.0 HTML/PDF renders succeeded (53 slides). Cover/bio/closing screenshots, layout bounds, footer links, and local images checked.
• YAML, output paths, local Markdown links, resource/catalog preservation, unchanged slide body, and git diff --check passed.
• Baseline and modified deck have identical pre-existing overflows: slides 8 (46px), 18 (67px), 20 (31px), 27 (33px), and 36 (31px). Presenter/closing slides fit; unrelated layout left untouched.
• No sample execution, subagents, or model-backed evaluations.

PDF publication is pending merge and a successful Pages deployment; no production deployment was run for this PR.
