fix(themes): P2 contrast floors retuned + gated across 9 themes (item 28b done)

18 hex retunes, hue-preserving OKLCH minimal raises except where the
upstream palette defines a canonical value: muted lifted to >= 2.0 on
lumon/white/retro-82/everforest (solved), gruvbox (bg4 #7c6f64), nord
(#616e88, the community comment-brightening), catppuccin-latte
(overlay1 #8c8fa1); text-on-surface >= 4.5 via surface nudges
(ristretto darker, latte lighter); accentAlt >= 3.0 (latte, summer-day
darkened); warn >= 2.5 — the bar's battery tint — darkened on the
light bases (latte, rose-pine dawn, summer-day) and flexoki-light's
four status colors moved to their canonical light-mode 600 series.

check-theme-contrast.py now gates all four adopted floors (7 pairings
x 21 themes, green). good/bad stay audit-only — identity themes sit at
2.0-2.3 there by design, so no exemption mechanism was needed. The
design audit's contrast findings drop 20 -> 1 (miasma's earthy `bad`,
kept as identity). Item 28 slice (b) complete.

Verified: V0, checks.theme-contrast green, flake check green,
re-audit. Rendering is V3 -> HARDWARE-QUEUE eyeball entries.

+## 2026-07-05 — P2 floors retuned + gated (iteration #33, item 28b done)
+- **Task:** item 28 slice (b) remainder — the P2 contrast floors.
+- **Did:** 18 hex retunes across 9 themes: muted raised on lumon/
+  white/retro-82/everforest (OKLCH hue-preserving minimal solve to
+  ≥2.05) + gruvbox→bg4 #7c6f64, nord→#616e88 (community standard),
+  latte→overlay1 #8c8fa1; text-on-surface via surface nudges
+  (ristretto darker, latte lighter); accentAlt darkened (latte,
+  summer-day); warn darkened on the light themes (latte, summer-day,
+  rose-pine-dawn) and flexoki-light's four statuses moved to the
+  canonical 600 series. check-theme-contrast.py gates all four
+  adopted floors (muted ≥2, text/surface ≥4.5, accentAlt ≥3, warn
+  ≥2.5 — warn is the battery tint); good/bad stay audit-only
+  (identity), so no exemption mechanism was needed. Slice (b) done.
+- **Verified:** V0 + checks.theme-contrast GREEN (21×7); re-audit:
+  contrast findings 20→1 (miasma bad = identity); flake check green.
+  Rendering is V3 → queued (P2 eyeball entry).
+- **Pending:** slices (c) per-surface polish (needs 1080p captures)
+  and (d) whole-swap bar parity; ansi[] conventions decision still
+  open (audit notes).
+- **Next suggestion:** slice (c) prep — 1080p captures via the VM
+  recipe, or hardware captures if Bernardo prefers eyeballing first.
