One decoration layer. Type, color, paper with rules. Same Markdown source.
The floor was low. The ceiling is not a free canvas.
Three layers. Stop there.
- Paper —
deckTheme: type, color, gradient, pattern - Frame —
@slideboard / tone / mark / kicker - Decoration — one painted surface: AIGC plate or shell

px KPI — drama from type, not from more chrome
AIGC is the decoration layer

Mood without a second theme

Pattern as field

Ornament set




Shells stay data
A chart is still decoration-with-data. Author names the series; runtime paints. No fake screenshot.
Series on stage
Enough vs excess
| enough | excess | |
|---|---|---|
| Paper | One theme stack | Per-page free hex |
| Frame | board + mark | Custom HTML layout |
| Decoration | One plate or shell | Stacked chrome |
Free HTML is freer. This is still a keynote stage.
Keep climbing
- Lock paper first (
deckTheme) - Frame every page (
@slide) - Add one decoration when the page needs atmosphere — AIGC plate or shell
