Hello 👋

I’ve refactored the theme component:

> <https://github.com/VaperinaDEV/discourse-topic-preview-modal/pull/12>
>
> The large \`topic-preview-modal\` component has been split into focused delegate c…lasses for nested topics, composer interactions, post actions, progress navigation, overlay watching, and back gesture state.
> 
> The existing component API and external contracts remain unchanged, while \`topic-preview-modal.gjs\` has been reduced from 1836 to 873 lines.
> 
> No functional changes intended.

The large `topic-preview-modal` component has been split into focused delegate classes for nested topics, composer interactions, post actions, progress navigation, overlay watching, and back gesture state.

The existing component API and external contracts remain unchanged, while `topic-preview-modal.gjs` has been reduced from 1836 to 873 lines.

No functional changes intended.
