A .csv already previewed — as raw text in a <pre>, columns lining up only if the file happened to be padded. It now renders as an HTML table with the first row as a header. The parser is a new pure lib/csv.ts (~50 lines of RFC 4180: quoted delimiters, "" as a literal quote, newlines inside quotes), so no papaparse. It never throws: null means "not a table" — an unterminated quote, or a file with no delimiter at all — and the caller falls back to the very <pre> it renders today. That fallback is structural rather than a second code path, because TextView gained a `delim` prop instead of a new component: it also keeps the ["text", fileURL] query key a restore invalidates and the retry:false a pinned ?v= version needs. .tsv is new here — it used to fall through to SniffView and render as text. The delimiter comes from the extension, never from sniffing. Big files are capped at 5,000 rows with the count stated on screen (virtualization is out of scope). Wide files scroll inside .csvbox, whose rules are scoped under that class on purpose: the file pane carries .markdown, and the plain .markdown table rules — including the ≤900px one that turns a table into its own scroller — would otherwise out-specify a bare .csvview and give the page two nested scrollers. Not doing: sorting, filtering, search, editing, XLSX.
