Not for most duff you mentioned, but the adbreaks themselves:

Our old dvr enabled us to skip ads in the recorded tv programs pretty accuratley. It set chapter markings whenever an ad-block began/ended which it figured out by the frequency of hard cuts as ads have them between every ad (so multiple times a minute) whlie normal programming usually does not. This was way pre-AI (like late 00s). Sadly the built in dvrs in our tvs after that did not have that function, but maybe there is a modern implimentation somewhere.

we have lever door handles at work and wheel and axle door knobs at home.

Aren’t those just standard door knobs? Like which others are there (besides maybe smarthome/electronic stuff, but that’s not really widespread esp. for home use)?
