not a change in this PR but just want to mention i don't like how we have:

@Suite("Form Data Decoding Tests")
struct FormDataDecodingTests {

It literally says the same "Form Data Decoding Tests" twice which is of little value.

[gwynne]

It says "Form Data Decoding Tests" instead of "FormDataDecodingTests". It's a small thing, but readability improves.

(I should specify that I'm referring to readability of the output during tests at runtime, not of the code.)

Can we also include the updated theme-settings.json for the DocC catalog? E.g.:

    "code":   { "border-radius": "16px", "border-width": "1px", "border-style": "solid" },
