v0.3.0

Added

• Source-provided image alternative text in image.alt and images[].alt, extracted from Open Graph and Twitter Cards and escaped in HTML cards.

Changed

• Update Huma to v2.40.0, golang.org/x/net to v0.62.0, and the image publishing login action to v4.7.0.

Fixed

• Preview and home-page caches respect upstream storage restrictions; a minimum TTL no longer extends explicit origin lifetimes.
• Thumbnail validators identify encoded bytes, not source URLs, and caching follows source freshness instead of claiming immutable content. New signed paths avoid previously immutable cache entries; legacy paths remain accepted.
• Standalone provider cards also receive a favicon fallback. Favicon fallback uses the page origin even with a CDN base URL, multi-size icons use their largest declared size, and SVG URLs with query parameters rank behind raster icons.

See CHANGELOG.md for every version.
