Devicon and PostCSS integration: class name stability across major versions

When integrating Devicon with a PostCSS‑based build pipeline, the goal is to maintain reliable icon display across project updates without unexpected breakage.

Devicon adheres to semantic versioning, where a major release can alter or drop icon class names such as devicon-git-original. PostCSS tools (e.g., cssnano, purgecss) may remove classes that are not detected in the source, increasing the risk of missing icons when class names change. Teams must decide whether to lock to a specific Devicon version, use version ranges, or implement a verification step that checks for class‑name changes before deploying.

What versioning strategy balances access to new icons with protection against breaking changes? How can a PostCSS configuration be adjusted to preserve Devicon classes that are referenced only via HTML templates? Which automated tests provide confidence that icon rendering remains correct after a Devicon upgrade?
