Description
Text halos are useful for improving legibility by applying an area of solid color around the text. However, they can be distracting when you can't be certain of what's in the background, and when there is a mismatch between background and halo colors.
_Ideally, the left label would have a blue halo to match the water. Labels over the park (right) would have a green halo to match that park.The center label with land-colored halo is ideal_.
How feasible is it, to add an option to inherit `text-halo-color` from the `fill` and `background` layers immediately below it, for each pixel of the halo?

Research direction
No implementation files, tests, or entry points are named. Start by locating the text-halo rendering path and how fill and background layers are represented, then determine whether per-pixel inheritance is feasible. Done would mean halos match the underlying layer colors, including the label examples described in the issue.
