Why: user feedback (2026-09-30) — the UI still lacked the polish and
modern feel of ZCode; per its design system (calm/dense/operational)
this is the R4 visual convergence pass.
Evidence:
- New icons.tsx: 32 Lucide-style linear SVG icons replacing every emoji/
glyph (grep for the old glyph set now returns 0 in components); brand
mark + workspace-icon mapping shared by sidebar, rail, login, menus.
- Login/change gates gain a wide-screen brand panel (gradient + radial
glows + feature list), segmented tabs, focus-ring inputs, glowing
submit; sidebar gets a solid accent New Task CTA, inline-icon search,
selected task with accent bar, hover-reveal row actions, account
footer chips; chat area gains floating rounded composer with focus
glow, calmer header/tool blocks, greener HITL confirmations, empty
state mark; modals gain backdrop blur + spring-in.
- Two headless review iterations on the real binary (--auth on, both
themes): fixed bubble padding, headline break, and lifted the panel
step for clearer three-column separation; final walk shows 21 SVGs,
zero leftover glyphs, zero console errors, build + vitest + full make
test green.
Impact: pure visual layer (CSS + icon components + class-level JSX);
no behavior, API, or state changes; both themes driven by the new token
scale in the ui repo.
