调研方向
Start with crates/tree-sitter-qmd/tree-sitter-markdown/src/scanner.c, especially the scanner dispatch and parse_ordered_list_marker, then trace how crates/pampa/src/pandoc/treesitter_utils/list_marker.rs stores and parses markers. The issue leaves open whether q2 should support these markers or warn and document their absence, so clarify that decision first. Done means the chosen behavior is explicit and the reproduction no longer silently renders list markers as paragraphs.

描述
Bug description
Pandoc reads a), A., (i) and #. at the start of a line as ordered list markers (the fancy_lists extension).
Quarto 1 has it on by default, and writes ol type="a", ol type="A", ol type="i" or a plain ol.
q2 only accepts digits in front of . or ), so every other marker stays text, with no warning.
A q2 design note for the docx import work already records that qmd has no fancy list markers.
That work reports the lost list style and leaves the parser as it is, so the note does not say whether q2 plans to support these markers:
Nothing tells a user, and a Quarto 1 document changes meaning without an error.
The scanner sends a line to parse_ordered_list_marker only when it starts with a digit, and that function has no branch for letters, roman numerals or #:
The marker is then stored as a number, and process_list_marker parses it as usize:
Steps to reproduce
index.qmd:
---
format: html
---
a) First
b) Second
Run q2 and Quarto 1 on it:
q2 render index.qmd --to html
quarto render index.qmd --to html
Actual behavior
q2 renders two paragraphs and the HTML has no ol:
<p>a) First</p>
<p>b) Second</p>
Quarto 1.12.0 renders an ordered list:
<ol type="a">
<li><p>First</p></li>
<li><p>Second</p></li>
</ol>
Expected behavior
The markers give ordered lists with the matching type attribute, as in Quarto 1.
If q2 does not plan to support these markers, the notes on differences from Quarto 1 could say so, and q2 could warn when a line starts with one of them.
