fix(theme): generated waybar/rofi CSS invisible on on-surface palettes (item 27)

Follow-on to the swaync fix (a643391): the generated Waybar CSS colored
the module row and #window @subtext and dim states @muted, and the
generated rofi theme put @fg text on @surface chips — invisible where
palettes use those roles as "on-surface" (flexoki-light: subtext==base,
surface==text; gruvbox: muted/base = 1.27). flexoki-light has no
whole-swap, so it ran this CSS. Generated surfaces only — the summer
whole-swaps are hand-authored and untouched.

- waybar: secondary text → alpha(@text, 0.85); dim states (inactive
  workspaces, DND bell, muted volume) → alpha(@text, 0.5).
- rofi: @dim → text+"80", @surface → text+"1a" (#RRGGBBAA fg tints).
- check-theme-contrast.py pairings/docs now cover all three generated
  surfaces; status glyphs (good/warn/bad on base, worst 2.05) are
  deliberately not held to a text ratio — raising them is palette
  design, a human decision.

Verified: V0; V1 (checks.theme-contrast green over 21 themes;
downstream-template-home builds; rendered waybar style has zero
@subtext/@muted/@surface; rendered custom.rasi shows fg-derived
tints). Honesty: NOT visually verified — V3 queued (flexoki-light
eyeball + dark-theme regression spot-check).

+- **Task:** BACKLOG NOW#27 — generated waybar/rofi CSS invisible on
+  on-surface palettes (flexoki-light runs it; summers whole-swap).
+- **Did:** waybar.nix generated CSS: module row + #window →
+  alpha(@text, 0.85); inactive workspaces / dnd / pulseaudio.muted →
+  alpha(@text, 0.5) (gruvbox's muted/base was 1.27). rofi.nix: @dim →

+  docstring/pairings now cover all three generated surfaces. Status
+  glyphs (good/warn/bad on base, worst 2.05) left as-is — palette
+  design, human call. Generated bar only; whole-swaps untouched.
+- **Verified:** V0; V1 — checks.theme-contrast green (21 themes),
+  downstream-template-home builds, rendered waybar style has zero
+  @subtext/@muted/@surface, rendered custom.rasi shows fg-derived
