Agent Skills: bento-slides

Create, edit, and validate self-contained Bento slide decks (`.bento.html`) by authoring the plain JSON document inside the `#bento-doc` script block. Use when Codex needs to turn source material into an interactive presentation, create a deck from the bundled Bento template, revise an existing Bento deck, or add charts, tables, morph transitions, state slides, motion, media, and speaker notes while preserving the embedded editor runtime.
