feat(tools): 1080p themed-desktop capture harness + first polish findings (item 28c)

tools/theme-shot.nix: boots the full themed desktop headlessly
(software-GL Hyprland, THEME env picks the slug) at 1920x1080 and
QMP-dumps desktop.png + menu.png (rofi root open) — the review
artifact for slice (c). Two fixes over the 2026-06-19 spike:
home-manager.useGlobalPkgs (the HM submodule otherwise misses the
overlay) and the menu shot via hyprctl dispatch exec. Maintainer tool,
deliberately not a checks.* gate. Known gap in the header: the
wallpaper needs ~/.nomarchy seeded in the guest.

First full-res review (tokyo-night) added to the item-28 punch list:
rofi root menu is ~760px of mostly empty row space (candidate:
right-aligned SUPER+CTRL hints from keybinds.nix), full-color Papirus
menu icons vs the all-monochrome bar glyphs is a [human] identity
call, bar right-cluster group margins confirmed at full res, and the
bar's alpha(text,.5) dim states should become the @muted role now
that 28b floors guarantee its legibility. Whole-swap bar module
parity verified textually — no drift.

Verified: harness end-to-end green (screenshots read back); evals
from tools/ via the relative flake path.

+review:
+  - **rofi root menu width:** ~760px for six short left-hugging rows —
+    either tighten, or use the space: right-aligned `SUPER+CTRL+<key>`
+    hint per row (keybinds.nix already knows them; discoverability
+    win).
+  - **Icon weight mix `[human]`:** full-color Papirus icons in the
+    menus vs all-monochrome bar glyphs — pick: symbolic/monochrome
+    menu icons for one system, or color as the menu's identity.
+  - **Bar right-cluster rhythm:** confirmed at 1080p — add group
+    margins (tray/net · stats · toggles · battery/notify) on the
+    gaps grid.
+  - **Semantic dim:** bar dim states are `alpha(@text, 0.5)` tints;
+    the palette's `muted` role is now floor-guaranteed (28b) — one
+    semantic source, use `@muted`.
+  - Harness gap: wallpaper needs `~/.nomarchy` seeded in the guest
+    (theme-sync reads runtime state there) — add before vibe-review
+    captures; whole-swap captures (summer-day/night) still pending;
+(d) the whole-swap themes brought to the same bar (module parity
+verified textually 2026-07-05: whole-swaps carry every functional
+module; omitting cpu/memory is identity). Visual work is
 V3-bound by nature — screenshots are the review artifact, hardware
 confirms.
