Standard heyawake rules apply but with irregular rooms
Shade some cells so that:
i. no two shaded cells are orthogonally adjacent
ii. a number in the top left corner of a room, if given, is the number of shaded cells in the room
iii. no continuous horizontal/vertical line of unshaded cells may pass through two edges
iv. all unshaded cells are orthogonally connected
You can try this on Penpa+. Enjoy!
If you need it, there is a hint below the image.
Hint: Throughout the solve, spot the dominoes which contain a shaded cell.

Solution code: For each row, enter the length of the longest continuous horizontal line of unshaded cells. For each 2x2 room, the number of shaded cells (in reading order). That is, 19 digits in total.

@Vebby: Thanks! I'll consider adding thicker borders next time. As Dandelo mentioned, any shade of grey (or black but that's worse) works for answer check.

I use grey instead of dark grey.

Very nice! Thanks S.E.!
Small suggestion for such puzzles on Penpa+: Using Edge -> Thicker for borders helps with visibility, especially after some cells are shaded dark.
