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.

+    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`.

+- **Task:** item 28 slice (c) prep — full-res captures for the
+  per-surface polish pass.
+- **Did:** tools/theme-shot.nix (maintainer tool, THEME env-driven):
+  full themed desktop headless at 1920x1080 via the memory recipe +
+  two fixes over the spike — home-manager.useGlobalPkgs (HM submodule
+  otherwise misses the overlay → 'nomarchy-theme-sync missing') and a
+  menu.png shot (hyprctl dispatch exec nomarchy-menu). Proven on
+  tokyo-night; both shots read. Findings → item 28 punch list: rofi
+  root width vs empty space (→ keybind-hint column idea), icon-weight
+  mix (color Papirus vs mono bar) `[human]`, bar group margins
+  confirmed, alpha-tint dim vs @muted role. Whole-swap module parity
+  verified textually (no drift; cpu/memory omission is identity).
+- **Verified:** harness runs end-to-end (exit 0, screenshots read);
+  eval from tools/ with relative flake path OK. Wallpaper still
+  doesn't paint (theme-sync needs ~/.nomarchy in the guest — fix
+  noted in the header for the next run).
+- **Pending:** capture summer-day/night (whole-swaps) + latte;
+  then the polish slices; icon-weight call is Bernardo's.
+- **Next suggestion:** run the retuned-theme captures + start the
+  cheap polish items (group margins, @muted adoption).
