-#!/bin/sh
-# Pre-commit: the docs pages under apps/docs/content (and the `/<num>` short
-# links in apps/docs/redirects.ts) are generated from work/1 by `bun run sync`,
-# and deploy.yml publishes whatever main holds. Regenerate them now and stage
-# what sync changed, so a solution, its page and its redirect land in the same
-# commit and a stale `## Solution` never reaches main.
-#
-# Sync reads the working tree, not the index, so the pages it writes only
-# match this commit when work/1 has nothing unstaged: an untracked or
-# half-staged solution would ship a page whose source is not in the commit.
-# In that case refuse and say what to stage.
-#
-# Only paths that became dirty during sync are staged. Anything already dirty
-# beforehand (hand-written `## Approach` prose in progress, a new index.mdx)
-# stays where the author left it.
-#
-# Bypass for a deliberate partial commit: git commit --no-verify
