The export styles pinned the last column of every table to one unbreakable
line (width:1%; white-space:nowrap) — right for a numbers column, wrong for a
two-column clinical table whose second column is the whole finding: the
table grew to the width of its longest sentence and iOS then inflated the
text in those cells, so the "Finding" column read in a bigger font than the
"Feature" column. The pin goes, and the sheet opts out of text inflation.
With citations switched off the answer is still grounded in the retrieved
sources; only the markers are removed. The stripper now also removes the
escaped \[1, 2\] form and [src] placeholders, which used to survive as text.

The old renderer rewrote the text: it found "[n]" with regexes, renumbered
them, and swapped the result back in — which broke inside `arr[2][1]`, inside
HTML attributes, and whenever two turns disagreed about what "[3]" meant. It
also had a fallback markdown renderer of its own for when the rewrite
produced something markdown-it would not parse.
Now "[n]" is an inline rule registered on the same markdown-it instance that
renders everything else. The parser decides what is prose and what is code, a
link, or a URL, so the rule never sees "[1]" inside a code span, and it steps
aside for "[1](url)". Math is two more rules on the same parser instead of a
regex pre-pass, so "$" inside a URL is no longer math.
Identity vs display: the stored "[n]" and each card's id are the source's
identity (sourceNumber) and are never rewritten. The number a reader sees is
the order of first appearance, computed at render time from the token stream
(orderSourcesByCitation), so "one, then seven" cannot happen and a saved chat
re-opens pointing at the same cards it was saved with. Stored messages and
sources are untouched; export and the modal resolve by identity.
Translated HTML gets the same links through a TreeWalker over text nodes
(linkCitationsInHtml) rather than a regex over markup.
Deleted: renderCitationLinks, normalizeAdjacentCitationClusters, the
fallback renderer (fallbackMarkdown/renderMixedList/renderFallbackTable),
renderLatexText, CITATION_SCAN. Tests that asserted rewritten text now assert
token output; harnesses that render for real are given a parser.
