Description

Adds a CSS-first, mobile-first responsive design system to the CurrenciCombo portal. The portal now adapts fluidly from 320 px phones to 2560 px desktops without layout shift, horizontal scroll, or unusable tap targets — and the workspace (IDE) bails gracefully to a dedicated mobile screen below md.

Full strategy, rationale, breakpoints, component inventory, and gotchas live in docs/ux-responsive-strategy.md.

What's in the box

Foundation — src/styles/:

  • tokens.css — breakpoints (--bp-xs 0 / sm 480 / md 768 / lg 1024 / xl 1440), fluid type scale and spacing via clamp(), motion, z-index, focus-ring, safe-area-insets.
  • responsive.css — all viewport-conditional overrides. Desktop behavior is byte-for-byte preserved (every rule is wrapped in @media (max-width: …) or @media (pointer: coarse)).
  • a11y.css:focus-visible ring, .skip-to-content, .sr-only, 44×44 px tap-target enforcement on coarse pointers.

Hooks — src/hooks/:

  • useMediaQueryuseSyncExternalStore-based subscription to matchMedia change events (no window.resize).
  • useBreakpoint — returns { current, isXs/Sm/Md/Lg/Xl, isMobile, isTablet, isDesktop }.
  • useReducedMotion, useOrientation.

a11y primitives — src/components/a11y/:

  • SkipToContent, VisuallyHidden.

Layout changes:

  • Portal topbar hides the environment badge and logo text below md so hamburger + logo mark + user avatar fit on a 320 px phone.
  • Portal sidebar becomes an off-canvas drawer below md (backdrop, Escape to close, closes on route change or resize-up-to-desktop, body-scroll-lock). Tablet (md–lg) forces the 56 px icon-only rail. Desktop (≥ lg) unchanged.
  • Dashboard KPI row uses repeat(auto-fit, minmax(min(100%, 180px), 1fr)) — six cards at xl → one card at xs, fluidly.
  • Tables get two patterns: horizontal-scroll wrapper (default) and opt-in portal-table--stack stacked-card mode at xs.
  • Login stacks columns below md, safe-area insets, 100dvh to avoid iOS Safari bottom-bar glitch.
  • Workspace (App.tsx) gates below md with a WorkspaceMobileGate — explains why the IDE isn't shown and deep-links to /dashboard, /transactions, /accounts. Pattern matches VS Code Web, Figma, Replit.

Global: viewport-fit=cover, theme-color, skip-to-content link, <main id="main-content" tabIndex={-1}> landmark.

Design rationale highlights

  • CSS-first. The only JS structure swap is the mobile drawer and the workspace gate. No ResizeObserver, no window.resize listener.
  • Fluid between breakpoints. Typography and spacing interpolate continuously from 320 → 1440 px via clamp(min, preferred-with-vw, max) — avoids hard snap at breakpoints.
  • No CLS. Fluid clamp() sizes; auto-fit grids; intrinsic-aspect-preserving media defaults; position: fixed drawer.
  • Accessible by default. Focus ring, skip link, landmarks, aria-expanded/aria-controls/aria-current, body-scroll-lock, Escape closes all menus.

Type of Change

  • New feature (non-breaking change which adds functionality)
  • Documentation update

No runtime behavior changes at ≥ lg desktop viewports — this is additive for smaller viewports.

Testing

Automated (this PR):

  • npm run build clean (tsc -b && vite build, 2075 modules, 510 ms).
  • npm run lint — net zero new errors (pre-existing 195 errors, post-change 195 errors). Two intentional inline eslint-disable-next-line react-hooks/set-state-in-effect comments synchronizing drawer state with router location.pathname and useBreakpoint().isMobile — the textbook "sync with external system" use of useEffect.

Manual (follow-up on this PR):
Viewport sweep across 320 / 375 / 414 / 768 / 1024 / 1280 / 1440 / 1920 / 2560 in both orientations plus 2× DPR, plus Lighthouse mobile + desktop on the vite preview build. Posting screenshots + scores as a comment thread.

Checklist

  • Code follows project style guidelines
  • Self-review completed
  • Comments added for complex code
  • Documentation updated (docs/ux-responsive-strategy.md)
  • No new warnings generated
  • Tests pass locally (build + lint at parity with main)
  • Screenshots across the matrix — following up as a comment thread

Screenshots

Additional Notes

CT 8604 cutover status: paused per prior guidance. After this PR merges, I'll resume the 10-step cutover block from earlier. Nothing in this PR affects scripts/deployment/.

## Description Adds a CSS-first, mobile-first responsive design system to the CurrenciCombo portal. The portal now adapts fluidly from 320 px phones to 2560 px desktops without layout shift, horizontal scroll, or unusable tap targets — and the workspace (IDE) bails gracefully to a dedicated mobile screen below `md`. Full strategy, rationale, breakpoints, component inventory, and gotchas live in `docs/ux-responsive-strategy.md`. ### What's in the box **Foundation — `src/styles/`:** - `tokens.css` — breakpoints (`--bp-xs 0 / sm 480 / md 768 / lg 1024 / xl 1440`), fluid type scale and spacing via `clamp()`, motion, z-index, focus-ring, safe-area-insets. - `responsive.css` — all viewport-conditional overrides.

nsatoshi added 1 commit 2026-04-23 04:51:14 +00:00
Adds a CSS-first responsive foundation with breakpoint tokens, fluid
typography/spacing via clamp(), and matchMedia-driven hooks. Portal
chrome swaps to an off-canvas drawer below md; workspace (IDE) shows
a friendly mobile gate below md with links to portal routes.

Runtime test results — PR #33 responsive UX/UI

Tested the vite preview build of this branch at desktop + mobile emulation, exercised drawer nav, workspace mobile gate, and ran Lighthouse at both form factors. All assertions passed.

Devin session: https://app.devin.ai/sessions/a33f9ebe303d413aab86e04252a1b4a1

Summary

assertion result
Desktop (1600×1122): no horizontal scroll, sidebar 220 px with text labels, hamburger display:none, KPI row shows 6 cards in one flex grid passed
Mobile (~375 px): hamburger button visible with aria-label="Open navigation" aria-expanded="false", all nav items marked offscreen passed
Click hamburger → aria-label="Close navigation" aria-expanded="true", nav items become visible (drawer opens with backdrop) passed
Navigate to /#/transaction-builder at mobile → Workspace Mobile Gate renders (<h2>Transaction Builder is designed for larger screens</h2> + "Go to Overview" / "View Transactions" / "Accounts" CTAs); full IDE does NOT render passed
Exit mobile emulation → /#/transaction-builder renders full IDE (TitleBar · ActivityBar · LeftPanel · Components · Canvas · RightPanel · BottomPanel) without reload passed
Lighthouse mobile on /#/login — Performance ≥ 70, Accessibility ≥ 90, Best-Practices ≥ 85 passed (96 / 93 / 96)
Lighthouse desktop on /#/login — same thresholds passed (100 / 93 / 100)

Lighthouse scores

category mobile desktop
Performance 96 100
Accessibility 93 93
Best Practices 96 100

All three categories comfortably above the PR's own target thresholds in section 7 of the spec.

Workspace mobile gate — the headline behavior

This is the core of Layer C1: at < md the IDE is replaced with a dedicated screen, not rendered-then-broken. A broken implementation would render the full multi-panel layout into a 375 px viewport. Instead you see three portal deep-links.

🟢 mobile /#/transaction-builder (gate) 🟢 desktop /#/transaction-builder (IDE)
Mobile workspace gate Desktop workspace IDE
<h2> text: "Transaction Builder is designed for larger screens". Three CTAs "Go to Overview" (primary), "View Transactions", "Accounts" Full IDE renders on same route when viewport returns to desktop — no reload.
Portal drawer — mobile chrome adaptation
🟢 mobile drawer closed 🟢 mobile drawer open
Mobile dashboard closed Mobile drawer open
Hamburger aria-label="Open navigation" aria-expanded="false"; sidebar nav items marked offscreen. Topbar shows logo-mark + notifications + user avatar only. Click hamburger → aria-label="Close navigation" aria-expanded="true"; all 9 nav items render; main content dimmed by backdrop.
Desktop regression spot-check

Desktop dashboard at 1600 × 1122 — six KPI cards in one fluid row, full sidebar with text labels, no horizontal scroll, hamburger hidden.

Desktop dashboard

Not tested

  • No physical phone / no real iOS Safari (only Chromium mobile emulation). The viewport-fit=cover + 100dvh + safe-area-insets CSS is inherited correctness from spec; I didn't test it on a real device.
  • Tablet md–lg icon-rail forced-56 px state was not captured as a distinct screenshot (Chromium mobile emulation is 375 px, not 768 px); the CSS rule exists in src/styles/responsive.css and is equivalent-by-construction to the mobile and desktop cases, but has no direct screenshot.
  • prefers-reduced-motion + prefers-contrast: more branches are media-query conditional; not exercised at runtime here.

None of these gaps affect the primary flow the PR is trying to prove.

Ready to merge?

All assertions in the adversarial test plan passed; Lighthouse exceeds all thresholds; no console errors observed during the sweep. Recommend merge, then I'll resume the paused CT 8604 cutover guidance.
