Star History #4

	name: Star History

	# Renders this repo's star-growth chart (light/dark SVG + PNG) into
	# assets/star-history/ and rewrites the marker block in README.md. The action
	# detects whether star data actually changed and only commits when it did, with
	# a "[skip ci]" commit message so chart refreshes don't trigger the CI workflow.
	# Daily schedule keeps commit noise low; use workflow_dispatch for an on-demand
	# refresh (e.g. the first run after merging this workflow).
	on:
	schedule:
	- cron: "0 3 * * *"
	workflow_dispatch:

	# Serialize refreshes so a manual dispatch can't race the scheduled push.
	concurrency:
	group: star-history
	cancel-in-progress: true

	# The action commits the refreshed chart and README and pushes to main.

	# Pinned to an immutable SHA rather than the mutable v1 tag: this
	# third-party action holds contents:write and pushes to the repo, so its
