Description
Describe the bug
If multiple load functions return data with the same key, the last one ‘wins’
https://svelte.dev/docs/kit/load#Layout-data
Q1: What does "last one" mean? how are load functions ordered? This is confusing as another section mentions that they run in parallel.
Q2: Are load functions ordered differently during SSR vs CSR. Are the following statements correct?
- In SSR, all load functions run in parallel
- In CSR, all server load functions then all universal load functions

Research direction
Start with the linked SvelteKit documentation sections for Layout data and Parallel loading. Trace the documented load-function behavior for key collisions and SSR versus CSR, then update the documentation so ordering and execution semantics answer Q1 and Q2 unambiguously.
