Why Sweden mobilized but did not intervene in Norway

Did Sweden consider intervening in the Norwegian campaign?

Sweden mobilized comprehensively to defend itself but did not enter Norway, maintaining armed neutrality while deterring a German attack on Swedish territory.

Sweden's response contrasted with the Norwegian government's hesitation. Sweden immediately called reserves, manned forts and borders, and sent ships to sea. That posture made clear that a German extension of the campaign into Sweden would meet organized resistance. The answer presents Swedish policy as armed neutrality rather than passivity or a ready commitment to rescue Norway.
