I played through the daily puzzle:
1. It was really hard in dark mode to see what I was doing
2. Scanning was almost impossible without clicking and seeing the runs -- so it was mostly fully pencil mark and find pairs and triples.
Overall, unique, but I think some further constraints or human-setters (as you mentioned) could lead to more intuitive or clever paths to a solution.
(Perhaps instead of lines, shade the cells in the runs to avoid clutter with borders and writing over numbers)
the puzzle now shows all runs all the time.
