base64-ng 0.13.0

hashavatar 0.13.0

0.13.0 expands the background catalog and applies targeted determinism
hardening without adding new avatar families.

Added

• Added seven AvatarBackground values:
  • polka-dot
  • striped
  • checkerboard
  • grid
  • sunrise
  • ocean
  • starry
• Implemented each new background in raster and SVG output.
• Added tests that prove the new raster backgrounds are distinct and that the
  new SVG backgrounds remain well-formed XML.

Changed

• Raster frame-shape hit-testing now uses integer arithmetic for circle,
  squircle, hexagon, and octagon masks. This reduces one source of
  platform-specific floating-point rounding in clipped output.
• Automatic style derivation can now map some identities to different
  backgrounds because AvatarBackground::ALL contains more variants. Services
  that need old automatic output should keep their existing namespace
  style_version until they intentionally migrate.
• Documentation now avoids cargo test --all-features guidance because
  blake3 and xxh3 are intentionally mutually exclusive crate-wide identity
  hash modes.
• README fuzz wording now reflects default WebP coverage and feature-gated
  encoder paths instead of describing PNG as always available.

Compatibility Notes

• Explicit AvatarOptions and AvatarStyleOptions selections remain
  deterministic for the selected kind, background, dimensions, seed, namespace,
  crate identity hash mode, and identity.
• The new background variants are public API and therefore affect automatic
  background distribution.
• No new avatar families were added in this release.
