Subject: [PATCH] presentation.org: fix empty separators + tables fit slides
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- H:2: ** headings = frames, * headings = sections (logical grouping)
- AtBeginSection{}/AtBeginSubsection{}: suppress empty section title slides
- shrink=15: auto-scale overflowing content up to 15%
- Tables: adjustbox max totalheight=0.72 textheight (fits slide)
- config.el tabularx filter skips beamer → plain tabular + adjustbox works
