preencha o interior de um caminho fechado construído aleatoriamente

Não tenho certeza de como proceder ao preencher o interior de um caminho gerado aleatoriamente (por meio de uma decoração aleatória).

Comecei com o código fornecido na resposta a esteperguntae trabalhei nisso já que o propósito básico estava relacionado.

imagem sim

O preenchimento e a linha desenhada não são exatamente iguais, pois há uma decoração aleatória aplicada a cada um.

PERGUNTA)

Como aplico o preenchimento no interior delimitado pela linha desenhada?

(Além disso, neste caso, como faço para aumentar as setas de decoração? Posso aplicar setas de decoração também no caminho desenhado sem quebrar a outra decoração?)

Você precisa reutilizar o mesmo caminho com postaction,preactionchaves.

Como você pode ver, random stepsnão jogue bem com a rounded cornersopção. Dê uma olhada tambémDeve \tikzset ou \tikzstyle ser usado para definir estilos TikZ?
