Summary

  • After feat(docker): Add KDE kimageformats for AVIF, JXL and additional image formats #505 lands, docker/Dockerfile and docker/Dockerfile.aarch64 are byte-identical — same base (linuxserver/baseimage-ubuntu:resolute, a multi-arch manifest), same package lists, same multi-stage layout.
  • This PR deletes docker/Dockerfile.aarch64 and points the existing docker-arm64 CI job at the shared Dockerfile.
  • Pins --platform linux/arm64 on the arm64 job to match the explicit --platform linux/amd64 already used by the amd64 job. Both jobs still run on their native runners (ubuntu-latest and ubuntu-24.04-arm) and the manifest-combine step downstream is untouched, so multi-architecture publishing keeps working.

Dependency

Stacked on #505. Must merge after #505 — the byte-identical state only exists once #505 lands. While #505 is open, this PR's diff will include the #505 commits; GitHub will narrow it down automatically after #505 merges.

Test plan

  • Verified locally on Apple Silicon: native arm64 build from the consolidated Dockerfile produces a working image with kimg_avif.so + kimg_jxl.so present; avif.cbz and jxl.cbz pages render end-to-end through the HTTP API.
  • After CI runs: confirm both docker-amd64 and docker-arm64 jobs succeed building from the single Dockerfile.
  • Confirm the existing docker buildx imagetools create manifest-combine step still produces a working multi-arch tag.

🤖 Generated with Claude Code

The amd64 and arm64 Dockerfiles became byte-identical after YACReader#505
landed the resolute base, kimageformats runtime, and the split
sevenzip-builder stage on arm64. Drop the duplicate and point the
docker-arm64 CI job at the shared Dockerfile; the linuxserver
'resolute' tag is a multi-arch manifest, so the same Dockerfile
builds natively on either runner. Pin --platform linux/arm64 on the
arm64 job to match the existing --platform linux/amd64 on the amd64
job.

Stacked on YACReader#505 — must merge after YACReader#505.
