amygdala stories: give content + resigned more settings

Training on 537c72bd46 showed grief_stricken successfully broke
out of the cozy cluster, but content (single scenario:
sunday_afternoon) took its place — pulled into couch-blanket
phenomenology at cosine 0.68-0.82 with cozy/sensual/resigned.

Same fix: spread each concept across multiple settings so PCA
has to find the valence axis, not the scene axis.

  content:  + finishing_the_patch, the_writing_session, park_after_rain
  resigned: + the_comment, the_long_meeting

Resigned had 2 scenarios (sunday_afternoon, waiting_for_results)
— both about accepting something unwanted in a slow/private
context. Adding work-context resigned (PR review you lost,
restructuring meeting) should pull it out of that cluster.

+I opened the laptop and saw the notification. New comment on the PR. I clicked through. Sarah had left a paragraph about the edge case we'd discussed last week. I read it through twice. She was right. She had been right when we'd sketched the pattern together and I had tried to take a shortcut anyway. There was no point in the back-and-forth I could already hear myself starting in my head. I closed the tab, made coffee, and came back. I started typing out the guard the way she had originally suggested. This was what the day was going to be now — writing the correct version instead of defending the version I had wanted to be correct.
