Type Alias: PhosphorIconName

type PhosphorIconName = string;

Defined in: packages/sdk/src/phosphor-icon.ts:14

Export name of an icon from @phosphor-icons/react — e.g. "Flag", "ArrowClockwise", "PushPin". The host resolves the name and paints it: toolbar chrome uses weight="bold"; tab decorations use weight="regular" by default (filled: true → weight="fill"); both use size="1em" so glyphs track UI zoom.

Use the PascalCase component name from Phosphor, not a kebab-case path.
