# Install Jupyter so Quarto can execute Python code cells in documents/decks
# -----------------------------------------------------------------------
# Quarto runs ```{python}``` cells through a Jupyter kernel. It uses the system
# python3 it detected (/usr/bin/python3), so Jupyter must be installed there.
# We install only the headless execution stack Quarto needs (jupyter-client +
# nbclient/nbformat + the ipykernel kernel + pyyaml, which Quarto's own
# /opt/quarto/share/jupyter wrapper imports), not the notebook/lab servers, and
# register a system-wide "python3" kernelspec under /usr/local/share/jupyter so
# it is discoverable regardless of HOME/XDG. Noble's Python is externally
# managed (PEP 668), hence --break-system-packages in this controlled image.
# The runtime user (www-data) writes Jupyter's runtime/connection files under
# its HOME (/var/www/.local), which is made writable in the Quarto step above.
# python3-venv is needed so a project's requirements.txt can be installed into
# a per-project venv (see QuartoRunner / PythonVenvGate).

# Install decktape + headless Chromium (for exporting RevealJS decks to PDF)
# -----------------------------------------------------------------------
# decktape drives a headless Chromium (via Puppeteer) to print the rendered
# reveal.js slides to a faithful, one-slide-per-page PDF. Chromium is the
# open-source engine (BSD); decktape is MIT, Puppeteer Apache-2.0 — all
# permissive and AGPL-compatible. They are invoked as a separate process
# (QuartoRunner runs `decktape ...`), never linked into the app.
#
# Puppeteer downloads its Chromium into PUPPETEER_CACHE_DIR during the global
# install; we put it in a world-readable /opt path so the www-data runtime user
# can launch it. Playwright is used only as a robust, distro-aware installer for
# Chromium's system libraries (handles Ubuntu Noble's t64 package renames).

# 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.
