'use server' / 'use client' とキャッシュの関係

Next.js のキャッシュは「サーバー側」と「クライアント側」の2層に分かれる。

ブラウザ（'use client'）
  └─ Router Cache
       ├─ 訪問済みページの RSC ペイロードをブラウザが保持する
       ├─ router.refresh() で破棄できる
 └─ revalidatePath / revalidateTag では破棄できない

# This is the configuration file for Ghostty.
#
# This template file has been automatically created at the following
# path since Ghostty couldn't find any existing config files on your system:
#
#   /Users/kousei_himeno/Library/Application Support/com.mitchellh.ghostty/config
#
# The template does not set any default options, since Ghostty ships
# with sensible defaults for all options. Users should only need to set
# options that they want to change from the default.
