Reintroduce Sturdy and Canary

 ## Things I've tried
 
-- After reading [Pascal Getreuer's guide][which-alt], I added experimental
-  layers for the [Sturdy][sturdy], [Canary][canary], [Gallium][gallium], and
-  [Focal][focal] layouts, curious to see if I might like one better enough to
-  switch away from Colemak-DH. So far, no, but I may return someday.
+Many of these are experimental layers for alternative layouts, largely inspired
+by [Pascal Getreuer's guide][which-alt]. I continue to play with these in the
+background, curious to see if I'll find something I like better enough than
+Colemak-DH to take the muscle memory hit.
+
+- Adding a [Focal][focal] layer. I may have given up too soon (it has nice
+  looking metrics!), but I had a lot of trouble with P on the inner index
+  column, bottom row. Maybe this teaches me I want to deprioritize the inner
+  index column in favor of heavier ring finger usage?
+- Adding a [Gallium][gallium] layer. I didn't like the pinky to inner index
+  lateral stretch for NG much. I've preemptively ruled out [Graphite][graphite]
+  for having the same feature. So I think this means I want low LSBs, which is
+  funny, because both of those layouts do have low metrics there. Maybe it's
+  just the NG that gets me.
 - Adding a Qwerty layer so friends could test-drive the keyboard more easily. I
   tried to gather interest over Christmas, and I think this is just going to be
   my own personal hobby, lol.
