Here's how I solved it.

Use line logic in between each paragraph.

Smile logic on the "A."

Internal edge logic on the 5 in row 26 tells you that it can't go in the first 10 columns.

Ditto for the 5 in row 35, so it has to go in columns 20-26. Then, if you place the second 5 in row 35 all the way to the right, there's a contradiction pretty quickly. So row 35 column 26 is a dot. Ditto for row 35 column 20. So the second 5 in row 35 spans columns 21-25.

Next, internal edge logic on the red 3 in column 15, moving bottom to top, places it in rows 13-15.

Next, try placing the black 3 in column 1 in rows 33-35. Contradiction, so column 1 row 35 is a dot. Then try it in rows 32-34. Contradiction, so column 1 row 34 is a dot. Then try placing the black 3 in column 10 in rows 33-35. Contradiction, so column 10 row 35 is a dot. Then try it in rows 32-34. Contradiction, so column 10 row 34 is a dot.

Then smile logic on the "Y".

And you're done!
