<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> Fixes Tron resource max handling and safe percentage calculation.
>
> - `useTronResources`: passes actual `max` values (can be `0`) to
`createResource`; percentage uses `Math.max(1, max)` to avoid
divide-by-zero while preserving displayed `max`
> - Tests updated to expect `max: 0` when no resources exist; existing
parsing and capping behaviors verified
>
