explainer-board-system

The look, layout and motion system for 16:9 YouTube explainer boards, in the "Clean minimal" starter theme (white paper, thin-bordered cards with one soft shadow, Inter / JetBrains Mono / Instrument Serif, one blue accent, footage tiles at true aspect, camera box bottom-right). Use whenever you design, build, review or animate an explainer board, slide, chart, diagram or end screen; when someone asks for the board colours, fonts, sizes, safe zones, camera keep-out, chart rules, motion, easings or word-sync rules; when choosing which board fits a line ("which board for a price breakdown?"); or when QA-checking boards before export. It owns how boards look and move; explainer-board-brief owns what goes on them.
