fix(emcn): normalize MoreHorizontal and TerminalWindow geometry

[waleedlatif1]

The sidebar row's ... renders visibly oversized. Root cause: MoreVertical was migrated to the house geometry and MoreHorizontal was left behind.

	viewBox	build	dot Ø	span
MoreVertical	-1 -2 24 24	stroke 1.55	1.78px	8.78px
MoreHorizontal (before)	0 0 12 3	fill	3.17px	14.00px
MoreHorizontal (after)	-1 -2 24 24	stroke 1.55	1.78px	8.80px

(measured at size-[14px])

They are the same glyph rotated 90°, in the same overflow-menu role. Because 12×3 is far wider than tall, a square size class scales by 14/12 and the dots stretch edge-to-edge, while every neighbour on that row sits well inside (Folder 9.7px, ChevronRight 9.4px, Lock 11.2px).

Redrawn as the exact transpose of MoreVertical about (10.25, 9.75) — same radius, same stroke, same 6-unit spacing. Both now measure 8.80px, mirrored (8.8×1.8 vs 1.8×8.8).

TerminalWindow — same class, found by the sweep

RESOURCE_REGISTRY renders ten icons side by side as tabs at size-[14px]:

Library 12.05  Task 12.05  Workflow 12.05  Connections 11.20
Database 11.20  Globe 10.30            <- all stroke 0.90
TerminalWindow 14.00  FILL  viewBox 0 0 16 14   <- lone outlier

Redrawn on the 24-box keeping its character (window + title bar + three chrome dots): now 10.85px, and the strip is uniform at 10.30–12.05px / 0.90px stroke.

Call-site changes that must ship with the viewBox change

• panel.tsx:696 passed no size inside <Button className='size-[30px]'>. Button has no [&_svg]:size-*, so the icon renders at its intrinsic size — it would have jumped 12×3 → 24×24 inside a 30px button. Now explicitly size-[14px].
• sidebar.tsx:274 and :1615 used size-[9px] — compensations for the oversized glyph (9px against a 12-wide box yields a ~9px span). Against the 24-box they would render 5.64px, so they move to size-[14px] → 8.78px, exactly MoreVertical.

Every other site was verified: 8 more MoreHorizontal sites already pass a square size; the two unsized ones sit inside DropdownMenuItemAction, which force-sizes [&_svg]:size-[16px]. All 6 TerminalWindow sites resolve to square sizes (3 explicit, 3 via caller className — resource-tabs size-[14px], recently-deleted size-5, ContextMentionIcon size-[12px]/size-[14px]). No aspect-ratio (h-[N] w-[M]) sizing anywhere in either call graph, so nothing letterboxes.

How this was found

All 168 icon components were measured by rendering each at 20× and scanning the alpha channel for its true ink bounding box, rather than estimating from path coordinates. Median span is 11.45px at size-[14px]. Both redraws were rendered against their real neighbours and visually checked before committing.

Verified not bugs

• Sim, Wordmark, Blimp — brand marks; Play — deliberately filled (PlayOutline is the stroke variant)
• BubbleChatClose/Preview — both 0 0 14 14 filled at 12.6px, but they only ever toggle against each other
• DocumentAttachment — 13.55px, but zero call sites (exported from the barrel, unused)
• The remaining >12.5px icons are all standard 0 0 24 24 / 0.90 stroke — that's glyph shape, not geometry

Checks

biome clean · type-check --force 23/23 (0 cached) · no test references either icon; the 5 sidebar collection errors are pre-existing — a pristine origin/staging worktree reproduces the same 5 with zero changes applied.

PR Summary

Low Risk
Visual/icon sizing only in emcn and a few UI call sites; no auth, data, or business-logic changes.

Overview
Fixes oversized sidebar overflow … icons by redrawing MoreHorizontal on the same 24-box geometry as MoreVertical (stroke 1.55, three circles) instead of the old 12×3 fill glyph that scaled too wide at square sizes.

TerminalWindow is redrawn the same way so it aligns with other resource-registry tab icons at size-[14px].

Call sites in panel.tsx and sidebar.tsx now pass size-[14px] explicitly—replacing compensating size-[9px] on the sidebar and avoiding a jump to intrinsic 24×24 in the workflow panel more button.

Greptile Summary

The PR normalizes MoreHorizontal and TerminalWindow to the shared 24-unit stroked icon geometry and updates affected overflow-menu call sites to preserve their intended visual size.

• Rebuilds MoreHorizontal as the geometric transpose of MoreVertical.
• Redraws TerminalWindow using the standard square viewBox and stroke treatment.
• Adds explicit 14px sizing where the previous icon geometry had required implicit or compensating dimensions.

Confidence Score: 5/5

The PR appears safe to merge with no concrete regressions identified in the changed icon geometry or affected call sites.

The new SVG strokes remain within their viewBoxes, MoreHorizontal matches its vertical sibling by construction, and current callers constrain both normalized icons to appropriate square dimensions.
