# render-social-card.sh — rasterise the OG social card SVG to a PNG.
#
# Discord, Slack, and some Twitter/X paths prefer PNG for OG images. The
# canonical source is the SVG (hand-edited with the site's palette); this
# script produces the PNG that docusaurus.config.ts points at.
#
# Usage: scripts/render-social-card.sh
# Requires: node + npx (bundled with Homebrew node).
#
# Re-run whenever the SVG source changes:
#   $ scripts/render-social-card.sh
