* comments

* comment

* move comment about the hardcoded address to buffers.h

* rewrite SYSTEM_HEAP_END_ADDR in terms of other symbols

* Use `ALIGNED` on all the buffers

* Rename SYSTEM_HEAP_END_ADDR to FRAMEBUFFERS_START_ADDR

* Put ALIGNED at the right like the rest of the codebase

* merge

* gLoBuffer

* gHiBuffer

* Add a static assert to ensure the address of gHiBuffer haven't shifted without the user noticing

* smol include cleanup
