   UI POLISH FRAMEWORK v1.0 — NORMATIVE RULES (Operator 2026-08-03)
   Full text: C:\CLOUD\SCRIPTS\Nexus\docs\UI_POLISH_FRAMEWORK.md
   Every polish change on any fleet surface must satisfy R1-R10:

   R1  AFFORDANCE   — controls look interactive; CTAs carry icon + label, no bare
                      ghost icons; icon-only requires tooltip + aria-label.
   R2  TOKENS       — colors/radii/spacing from --uif-* (or app :root vars); an inline
                      hex that should be a token is a defect.
   R3  FULL-WIDTH   — inputs/selects/textareas fill their form column (width:100%,
                      box-sizing:border-box); wrapper-div flex-stretch trap checked.
   R4  STATES       — :hover, :active, :focus-visible, :disabled on every control;
                      states live in CSS, never inline onMouseEnter JS.
   R5  RESPONSIVE   — verified at 375 / 768 / 1440; labels collapse to icon chips on
                      narrow widths; touch targets >= 44px on phones.
   R6  A11Y         — aria-labels on icon-only controls, contrast >= 4.5:1, visible
                      keyboard focus.
   R7  FEEDBACK     — toast/spinner/friendly error for every action; no silent no-ops.
   R8  REUSE        — window.UIKit components + established patterns; components born
                      in C:\CLOUD\SCRIPTS\Nexus\components\, served at /lib/.
   R9  SURGICAL     — polish never changes functionality; CSS append-only layers.
   R10 GATE         — Babel-on-disk + cache-bust stamp + served-file check + live
                      browser screenshot. A green disk check alone is NOT proof.

   MODEL ROUTING (same directive): UI work goes to QWEN models (crew_config UI profile,
   job_router UI worktype); reasoning + most work goes to DEEPSEEK-V4-FLASH.
