What is xsvg?
A graceful-degradation superset of SVG that compiles to a plain, static SVG file.
How it compiles
The lowering pipeline — one Rust compiler on two platform backings, verified pixel-identical.
Graceful degradation
What a plain SVG viewer does with raw, uncompiled xsvg — the contract that keeps files from breaking.
Namespaces & prefixes
The prefix policy — when an extension is unprefixed, x:-prefixed on an element, or plain inside one.
