First deploy night — Railway + auto-migration, dynamic PORT, Dockerfile fixes, energy-beam finish

What happened

First deploy night for Ki Clash on Railway, with some front-end polish on either side of the deploy work.

The deploy setup landed in a few steps:

• Added Railway deployment config with auto-migration via a new Dockerfile and railway.toml (2ba8dfa).
• Fixed the container to bind to a dynamic PORT instead of a hardcoded value, editing the Dockerfile (23a9a0f). This is a standard requirement for Railway-style platforms that inject the port at runtime.
• Added migration-status logging in railway.toml to debug the deploy (76983bf).
• Fixed Dockerfile COPY ordering and embedded the start command, touching both Dockerfile and railway.toml (20dafa4).

Note: no error text or specific failure symptom appears in any commit subject (only "debug: log migration status"), so none is reproduced here.

Front-end polish around the deploy

Earlier the same night, animations were slowed down and fighters made to animate independently (bac38a5), then dynamic fighter animations with per-action effects were added (8309958) — the polish leading into the deploy.

After the deploy config, the dramatic match finish and a visible energy-wave beam shipped across the battle/effects front-end (547925f), touching BattleArena, PixelEffects, PixelFighter, and pixel-art-types.

Housekeeping

• Merged the founding-philosophy branch into main (bf941d6) — an empty-file-list merge commit.
• Commit 0b58547 ("last") edited railway.toml and added a test-animations page plus web package changes; intent is not fully groundable from the subject alone.
• Closed out the session by adding a comprehensive project guide for interview prep at docs/PROJECT_GUIDE.md (2e67e41).

Notes

• All what/why points are grounded solely in git commit subjects and changed-file lists; diffs were not inspected.
• Date tension: two commits (bac38a5 at 2026-02-22T23:15:28+09:00 and 8309958 at 2026-02-23T00:32:08+09:00) straddle midnight JST. The frontmatter date is set to 2026-02-23, the majority committer date of the deploy cluster.
