This is a combination of two previous questions (with their respective answers):How to create a command for the sections with an svg next to it on the top of the page? and How to make a conversation with rectangle shapes using tikzpicture environment?
The problem
Please consider this MWE (it is long because I need to show the actual header and footer):

This combined source code comes from @Schrödinger's cat who kindly made modifications once the answers of the cited questions were accepted.
Look at the output:
There is a missing header. And sometimes it collides with the shapes.
Moreover, if we, for example, increase one image size, let's say we change \You[start,image={scale=1}]{example-image-duck} to \You[start,image={scale=1.35}]{example-image-duck}, there is a collision with the footer:
Question
Is there any way to prevent these collisions with the header and footer, preserving sizes? I don't care if one shape that does not fit in the page must go to the next page. I don't want collisions.
\usepackage[a4paper,margin=.25in,top=2cm,bottom=2cm,footskip=0.25in]{geometry}or something like this, i.e. just increase the margins? – Feb 25 '20 at 16:07topandbottomvalues then the first page has a lot of space between the green and white shapes. In the second page, the section still missing: https://i.imgur.com/yXTGn0r.png I will try changing its value to obtain a better result, thank you! – manooooh Feb 25 '20 at 16:16tcolorboxpackage, which allows you to produce breakable variants of such shapes. Now that I see that some of them are enormous, I am tempted to suggest to redo them intcolorboxto make them breakable. This would cure the problem of huge gaps when the last big shape does not fit on the page. – Feb 25 '20 at 16:20tcolorboxwill be worth for image shapes, too? Because in my document I will mostly use images, some text and some sample code. – manooooh Feb 25 '20 at 16:27frame code. – Feb 28 '20 at 19:58
