# Install TeX Live (for compiling .tex projects with latexmk)
# -----------------------------------------------------------------------
# Verso compiles .qmd with Quarto and .tex with latexmk; both engines live
# side by side.
#
# MINIMAL install (current): the upstream-Overleaf approach — scheme-basic
# (~300 MB) plus a few essential packages via tlmgr. Fast to build and small.
# Many documents that need extra packages (tikz, beamer, siunitx, extra
# fonts, ...) will NOT compile out of the box; users can be told to keep
# those projects in Quarto/Typst for now.
#
# TO GO FULL LATER (when the project is mature): change
#   selected_scheme scheme-basic  ->  scheme-full
# and optionally drop the explicit `tlmgr install` line. That single change
# restores a complete LaTeX toolchain at the cost of size/build time.
# Alternatively add individual packages to the `tlmgr install` list below.
