dig-urn-resolver 0.4.0

//! Authoring tool (run ONCE, then commit): emit the branded error SVGs into
//! `assets/` from the crate's `images::svg` source of truth. After running this,
//! rasterize each to a 512×512 PNG (committed alongside; the crate embeds the PNGs):
//!
//! ```sh
//! cargo run --example render_error_images
//! for f in assets/error-*.svg; do resvg "$f" "${f%.svg}.png"; done
//! ```
//!
//! Rendering happens ONCE at authoring — there is NO runtime SVG-raster dependency.
