What it actually parses

title: "Shipping a changelog"
draft: false
tags: [release, writing]
# a comment, ignored

key: value and inline [a, b] lists, both on one line. Quotes around a value (single or double) are stripped; everything else is read as a plain string, including false and 12 - there is no type coercion, so readString(meta, "draft") gives back the string "false", not a boolean.

Why it stops there

This is deliberately not a YAML parser: no anchors, no nesting, no block scalars.

title: &ref Anchors
subtitle: *ref     # not read - this is a plain string "*ref"
nested:
  key: value       # not read - nesting is not walked

Content files in this repo only ever need flat keys and flat lists, and @tanstack/markdown already stops handing back structure at the same boundary. The honest fix for a file that needs more is a real YAML parser, not teaching this one another feature at a time until it is a worse one.
