Code Review

This pull request centralizes deck metadata—including titles, speaker information, and export filenames—into a single deckMeta.js configuration file, with corresponding updates to the documentation and the OverviewSlide component. Additionally, it includes visual refinements to the halo-mark decoration within the presentation frame. A high-severity issue was identified in OverviewSlide.jsx where attempting to render the speaker object directly could cause a React runtime error; a code suggestion was provided to ensure the component safely handles both string and object metadata types.

Pull request overview

Refines the presentation’s “halo mark” decoration and centralizes cover speaker info into shared deck-level metadata, with documentation updates to guide future edits.

Changes:

• Updated the halo mark layout (restored corner, rotated dot cluster, and adjusted sizing/positioning).
• Moved cover slide speaker data into src/content/deckMeta.js and consumed it from the cover slide.
• Documented the new deck metadata shape/usage in README.md, README_ZH.md, and AGENTS.md.
