Restore the type squares in the results grids

[MDA2AV]

The little type squares next to every framework in the results grids stopped rendering after #1017.

Cause

All five type colours lived on one line:

.tsq-flagship{…} .tsq-emerging{…} .tsq-experimental{…} .tsq-engine{…} .tsq-infrastructure{…}

so deleting "the infrastructure badge rule" deleted the whole line. Every other removal in #1017 was correctly scoped — the filter pill, the tooltip, the abbreviation, the localStorage whitelist, the isScored branch and .b-infrastructure were all infrastructure-only. This one wasn't, because the line was shared.

.tsq kept its width, height and border-radius but lost every background, so each square rendered as a 10×10 transparent box. Both grid renderers still emit class="tsq tsq-<type>" — the markup was fine, there was just no colour to paint. The yellow tuned ring kept showing because it's an ::after with its own background, which is exactly why the squares looked like they vanished from beside an otherwise intact marker.

Fix

Restores the four surviving colours at their original values — unchanged, and still matching the .b-* badge and filter-pill palette:

type	colour
flagship	#2e9e6a
emerging	#3b73c4
experimental	#d98e2b
engine	#cb5f51

One rule per line now, so removing a tier can't silently take the others again.

Verification

Headless Chrome against the real data.js/docs.js, run on this branch and on main for comparison:

filter	main	this branch
flagship + emerging	51/51 transparent	0/51, correct colours
engine	26/26 transparent	0/26, rgb(203,95,81)
experimental	2/2 transparent	0/2, rgb(217,142,43)

Checked in both grid renderers (composite table and profile grid) and in dark mode; the tuned ring still renders.

Closing as a duplicate — this is already in main via #1025 (squash-merged as 36938032). I re-created it from the same branch after GitHub's PR API recovered, not realising you'd already opened and merged it; --author @me hid #1025 from my listing.
