this path gets redirected to a canonical - even if nonpermanent - one at
`{repo}/src/branch/{main-branch}/{path-to-file}`, that is
`{repo}/src/branch/development/{path-to-file}` in concrete terms.
the previous paths were resulting in 404s.
make report include `report_base.tex` file verbatim and save it in
`out/tex/report.tex` as a base file of the report.
currently, this is done when running `go generate ./report` but there
are plans to switch from that to emitting the file during runtime, as is
done with all other templates.
