Before changing any code, ask me where it should go — which project/theme, which page or template, and the position (e.g. after the hero) — and whether the target is a Shopify theme or a plain HTML site, unless I already said; restate the plan and wait for my OK. Then follow the repo's AGENTS.md: keep the blko- class prefix and CSS tokens (with fallbacks), keep custom elements idempotent, don't touch unrelated code, run `shopify theme check` for Shopify targets, and finish by telling me how to add/arrange it (Theme Editor steps for Shopify).
