No worries at all. Both approaches (mapping bike lanes as separate ways vs adding cycleway tag to the main road) "are in use today, and there is discussion about when to prefer which method", as documented on https://wiki.openstreetmap.org/wiki/Bicycle. So there are no hard rules about mapping bike lanes. Only community consensus and standards from local mapping groups. AI tools like ChatGPT can be useful in cases like this because they can aggregate and summarize long discussions happening on OSM forums.
