Feature request: expand beyond Savchenko to other textbooks

Several users have suggested expanding the platform to cover other physics problem collections beyond Savchenko. The most requested are:

• Irodov — "Problems in General Physics" (very popular in India and Russia)
• Chinese physics olympiad problems — collections used in CPhO preparation
• Kvant magazine problems

What do you think — should we expand scope, or stay focused on Savchenko? How would we maintain quality if we broaden the collection?

This came up in our user survey multiple times. The main concern is quality: Savchenko solutions are peer-reviewed by 72 contributors. Expanding to Irodov would need a similar contributor base. We could start with a separate section and see if the community forms around it.
