Adapt it.

Replace map data with climate-related geographical information (e.g., temperature zones, sea-level rise areas).
Update text content in DynamicMapFill to reflect climate data or policy names.
Modify DiplomacyPanelReveal to display 'Policy Impact' or 'Simulation Outcome' data.
Adjust InteractiveCursorHighlight to simulate drawing climate mitigation strategies or data points.
Change the primary color palette to reflect environmental themes (e.g., greens, blues, earth tones) while retaining the dark background.
Ensure sound design cues align with the new product's theme, maintaining the epic and dramatic feel.

Synthesizable in Remotion · key components of the pax-historia-geopolitical-sim template.

DynamicMapFill

Geographical regions on a map dynamically fill with solid colors, often accompanied by text labels appearing over the filled areas. The fill animation is quick and precise.

+ Code construction recipe

Utilize SVG path data for country/region outlines. Animate the 'fill' property of these SVG paths using `interpolate` with `ease-in-out` timing. Text labels can be rendered as `AbsoluteFill` children with `spring` animations for position and opacity.

DiplomacyPanelReveal

Information panels, typically dark rectangles with white text, slide in from the side of the screen, revealing dialogue or event summaries. They often have a subtle shadow or border.

+ Code construction recipe

Implement a `Sequence` of `AbsoluteFill` or `AbsolutePosition` components. Animate the `translateX` property using `spring` for a smooth slide-in effect. Text content inside can use `FadeIn` or `Typewriter` effects.

InteractiveCursorHighlight

A white cursor icon moves across the screen, highlighting interactive elements or drawing custom shapes on a map. The movement is fluid and responsive.

+ Code construction recipe

Create a `Cursor` component with an SVG icon. Animate its `x` and `y` coordinates using `interpolate` or `spring` to simulate user interaction. For drawing, use `Canvas` or SVG `path` elements with `stroke-dashoffset` animation.
