Remarks

The UI Toolkit replacement for CanvasCrawler, which walked a Canvas hierarchy and wrote colours onto Image, Text and Selectable components. The shape of the job is the same; what it walks is different. Panels are found by their theme USS class rather than by component type, which is both cheaper and more precise — .fish-bar__fill--hp names the health bar directly, where the crawler had to infer it from where an Image sat in the hierarchy.

Why inline styles and not the tokens. FishMMO-Theme.uss declares its palette as custom properties, which is the natural place for an override to land — but UI Toolkit exposes no runtime API for setting a custom property on an element, and a StyleSheet cannot be authored at runtime either. Custom properties are therefore an authoring convenience only. A live override has to be written as an inline style, which sits above USS in the cascade and is cleared with UnityEngine.UIElements.StyleKeyword.Null to hand control back.

What that costs. Inline styles have no pseudo-state, so an override applies to an element's resting appearance and its :hover / :active rules continue to come from the stylesheet. The Canvas theme crawler had the same limitation for the same reason — it wrote a Selectable's normal colour and left the ColorBlock transitions alone — so this is the behaviour being reproduced, not a shortfall against it.

Panels register on show rather than being swept globally, because each UIDocument owns a separate visual tree and there is no single root to walk from.
