TOML frontmatter interprets bare dates like 2022-10-31 as date literals requiring time components, causing parsing issues. YAML handles dates as strings by default, avoiding these problems. Changes: - export.ex: Add org-hugo-front-matter-format set to yaml - index.ex: Update title regex to match YAML format (title: vs title =) - quartz.config.ts: Use default FrontMatter plugin (YAML) instead of TOML
