Where (Precisely) do Line Effects Originate?

I'm finding the rules on the origination point of line effects to be ambiguous (essentially non-existent). I'm looking to the hive-mind to see if someone can find some rules that I have overlooked.

Line (CRB Page 457) wrote:
A line shoots forth from you, following a straight path in a direction of your choosing. The line affects each creature whose space it overlaps. Unless a line effect says otherwise, it is 5 feet wide. For example, the lightning bolt spell’s area is a 60-foot line that’s 5 feet wide.

I see that 2E removed the 1E verbiage "It [the line] starts from any corner of your square and extends to the limit of its range or until it strikes a barrier that blocks line of effect." That indicates that the line effect no longer is required to start from a corner.

Conversely, the templates on page 456 seem to show that line effects do originate from a corner. So maybe the line does originate from a corner.

I'm confused and would appreciate any help.

What is the origination point of a line effect?
1) The center of your square
2) The corners of your square
3) Any point within your square


Looking at the grid map for areas it looks like the line still originates from a corner of your square. Since there is nothing in the rules text to contradict this, and in fact it says to just look at the grid map, then I would go with that.

Caster picks a corner of their square and an area template to use. Spell affects squares in that area.

Which does make it either difficult or dangerous to target an enemy that is in your square with a line spell...
