### Changed
+- The mark's small-size variant — the tab icon and the `SP` initials it
+ carries — sets its S in Medium where the wordmark sets it in ExtraLight.
+ Against the P's SemiBold the ExtraLight S is a 0.90 stem against 3.40,
+ which at 16px is a quarter of a pixel against most of one, so the pair
+ rasterised to a P with a smudge beside it. Medium gives up the
+ Self/Post weight play, which needs more pixels than this variant exists
+ to work in, in exchange for both letters being there. The variants big
+ enough to carry the contrast keep it. `favicon.png` is regenerated to
+ match, and the outlines are IBM Plex Sans as before — the same
+ font-size, letter-spacing and baseline, with only the S's weight moved.
- The stamp's `SELF-HOSTED SMTP RELAY` line is set at 11.5/0.15 instead of
7.2/2.8, and no longer carries `opacity=".78"`. At the old size its stems
rasterised to about half a device pixel, so more than half its ink landed
