   mode-photoshop2026 — refined visual layer for the Photoshop
   experience. Reuses photoshop's tool layout and palette via the
   alias in modes.js; only the chrome differs.

   Design language:
     - very dark cool grays (#1a1a1a / #232323 / #2d2d2d / #393939)
     - Adobe-style blue accent (#2563eb / #3b82f6)
     - flat panels, 1px black separators, no gradients
     - tighter typography, system font stack
     - minimal hover/active states with the accent
