paper2beamer

Turn a paper PDF into a compiling Beamer deck, shaped by the user's intent and a pluggable theme. Read references/pipeline-overview.md first for the big picture.

Preflight (defensive — check before starting)

• Required tools on PATH: xelatex, latexmk, uv. If any is missing, tell the user and stop.
• Input must be a PDF. No arXiv id / LaTeX source ingest in this version.
• Pick the theme. Default is the bundled Simple theme with its pre-built paper2beamer/isa/Simple.yaml. If the workspace template/theme.tex selects a different theme and no isa/<Theme>.yaml exists, run references/isa-setup.md first.

Optional setups (bypassable, run once, persisted)
