md() split a block into physical lines and made each one a unit. Task
files are hard-wrapped at ~74 columns, so the second line of an item
became its own bullet, `- [ ]` rendered as a literal bracket pair,
nested lists flattened, and prose kept the author's ragged edge as
<br>. "Enough for these task files" was exactly what it was not.
Lists are now grouped into logical items before rendering: a new item
begins only at a marker, and a line without one is continuation text
joined with a space. Indentation is honoured — a marker past its level
opens a nested list, a shallower one closes back to the level that
fits — and one entry point serves both bullets and ordered lists, so
an <ol> nests under a <ul> the same way. Task-list items render as a
glyph in a span, never an <input>: the file is the source of truth and
the drawer is not an editor. A ticked box reads as settled (--calm);
an open one stays neutral. Paragraphs and blockquotes join their
source lines with a space, so prose reflows to the drawer's width.
Fences, tables, headings and rules are untouched, including the fence
state machine that spans blocks.
The tests lift esc() and md() out of the page and run them under node,
because the renderer is a pure function and its output is what to
assert on; node is not a bench dependency, so those checks skip when
it is absent and source-level invariants cover the shape of the fix.
One check renders every card on the board plus AGENTS.md and asserts
one bullet per source marker — the acceptance criterion applied to the
whole corpus.
