Based on the original working template (commit 4ceaea1):
- Same allowframebreaks via renewenvironment{frame}
- Same adjustbox wrapper on tabular (proven to work)
- Added: Kyndryl palette colors over Madrid theme
- Added: H:2 + AtBeginSection{} (no empty section slides)
- Added: logo via titlegraphic
- Added: rowcolors for alternating table rows
- config.el tabularx filter skips beamer (adjustbox handles it)
