leptris, the XML parser with hard bounds

Why it surfaced

leptris gives systems programmers a concrete promise: one arena per parse, a stated memory ceiling, and no hidden per-node allocations. Its presentation is unusually memorable for a developer tool, pairing detailed benchmark and conformance claims with the three-hares motif from Dunhuang and European church art.

A pure-C99 XML 1.0 parser, XPath 1.0 engine, and SAX interface built around bounded memory and zero required runtime dependencies.
