Remote junior dev — I quietly worry I'm learning way slower than I would in an office

First job is fully remote and I'm grateful for it, but I wonder if I'm missing all the osmosis stuff — overhearing seniors debug, quick 'hey how does this work' questions. I can go a whole day barely talking to anyone, and when I do ping someone I feel like I'm interrupting.

For folks who started remote: did you feel behind? What actually helped you learn faster and feel less isolated?
