Welcome to the forum
That’s a good question.
Some time ago, a community member posted a list of a few of the branch names and the platforms they correspond to. This doesn’t seem to be officially documented anywhere, so I’ve wanted to keep it updated. I forgot about the Chromebook, people don’t post about it much.
Out of the branch names available, maybe dogwood for the Chromebook.
Perhaps you could verify. The framework_tool will show the version numbers for all the Framework firmware currently in your laptop, including ther EC, github.com/FrameworkComputer/framework-system.
framework_tool --versions
result for FWL13 AMD Ryzen AI 300

How to find out which EC-Tool-version my FW is on - #2 by basert
It looks like the ectool will also provide it, github.com/DHowett/framework-ec#ec-version-strings.
If I recall, the ECtool offers the ability to temporarily change keyboard key mapping. FWL13 keyboard matrix, howett.net/data/framework_matrix
For flashing the EC, howett.net. I also ran into instructions here, community.frame.work/t/tracking-battery-flipping-between-charging-and-discharging-draws-from-battery-even-on-ac/22484/234.
