Detailed Description

A parsed header that OWNS its backing bytes.

The raw ::Header pointer is deliberately not exposed: a caller could retain it past this object's destruction and read freed memory. Internal decoders reach it through detail::HeaderAccess.

Read and validate the file preamble and header.

Takes SHARED ownership so it can construct its own per-query BufferedRangeReader internally (over-fetching the header plus the top R-tree levels in one request, as the Rust HTTP reader does).
