The Problem

Werkator uses maxMutationCrap as a ratchet: 650, just above today's highest value, lowered with every refactoring towards 15.
With codeCharta { colorRedFrom = 12 } the link set colorFrom=12&colorTo=12: green below 12, red from 12, no yellow.
Yellow started at half of maxMutationCrap, 325, capped at red.
It thus hung on a limit that a ratchet holds only for a while.
The KDoc of colorRedFrom, "yellow starts at its half", read as half of colorRedFrom, which it was not.

The Scenarios

@MC-CC-030 (changed) with colorRedFrom set, yellow starts at its half: colorFrom=6&colorTo=12 for 650 and 12.
@MC-CC-031 (new) codeCharta.colorYellowFrom sets where yellow starts; above where red starts the export fails.

The Solution

CodeCityPage.colorRange halves colorRedFrom for yellow when it is set, else the limit, as before; without a limit 5 and 9 as before.
codeCharta { colorYellowFrom } in the DSL; the export task checks it before it writes anything.
The KDoc of colorRedFrom says which value yellow halves.
Version 0.17.0: new behaviour and a new DSL key.

Afterwards

Werkator takes the new version with its next feature pull request, not with one of its own.

With codeCharta.colorRedFrom set, yellow starts at its half, not at half
of maxMutationCrap: a ratchet of 650 with red from 12 now links
colorFrom=6&colorTo=12 instead of no yellow at all.
codeCharta.colorYellowFrom sets where yellow starts, at most where red
starts (@MC-CC-030 changed, @MC-CC-031 new).
