Before visual work on SumTex gameplay surfaces, inspect the xAI reference saved at /home/krisyotam/dl/xai-style.html and its assets in /home/krisyotam/dl/xai-style_files/.
The current play surfaces should follow that reference: black canvas, large sparse type, thin dividers, muted secondary text, outline pill controls, and no blue UI.
Profile/activity design should follow /home/krisyotam/src/notes.krisyotam.com/src/app/activity.
