Summary

A usability and accessibility pass for people who use apps every day but are busy: fishers, chefs and fishmongers, often on a phone with wet or gloved hands, in glare or a dim kitchen.

This PR does not adopt the look of Grace Communications, namanet.org, the National Family Farm Coalition or localcatch.org. This environment's network policy blocked all four sites (and search returned no design details), so nothing here is derived from them. The current July 2026 brand (teal / terracotta / yellow, Inter) is unchanged. Tokens are now centralized, so a palette or font pass once the sites can be reviewed is a small change (see docs/DESIGN_SYSTEM.md).

Readability fixes

  • Dark-mode headings on About, Data Sources, Community and Upload used text-brand-teal (~2:1 on the dark background) and were nearly invisible. Light-mode helper text was 2.6:1 and terracotta links 3.6–4.0:1. All text pairs now meet WCAG AA.
  • New theme-aware tokens: text-accent, text-link, text-success, text-danger, border-line-strong, bg-primary, bg-brand-cta. Existing text-brand-teal / text-brand-terracotta / text-red-500 text uses were migrated by codemod.
  • SyncStatusBadge sat on the teal navbar with teal/gray icons (invisible spinner and offline state); it now uses light colors.
  • About's donation button was white on terracotta at 4.0:1; it now uses bg-brand-cta (5.4:1).
  • New app/src/lib/__tests__/designTokens.test.js fails if any token pair drops below its contrast target.

Calculator

  • Two numbered steps ("Your fish", "Your numbers") with plain-language labels: "What you have", "What you're making", "Pounds to buy".
  • 48px controls and 16px input text (no iOS focus-zoom); pressing Enter calculates; the disabled button explains why.
  • The result is a large numeral, announced to screen readers, and scrolled into view on phones.
  • Help tooltips (D/H-On, Round, ...) were hover-only, so they never appeared on phones. They now work on tap and keyboard, stay on screen (including under pinch-zoom), and close on outside tap or Escape.
  • Labels are bound to their fields. The "Applied to weight" select now appears only once a processing cost is entered.
  • "Sign in" uses a router Link, so a calculation isn't lost to a full page reload.
  • The calculation math and the save/export handlers are unchanged (diffed against main). The additions in the logic block are a result ref, a scroll effect, and a snapshot of the yield and target weight taken when a result is computed, so the text under the number can't drift from it if those fields are edited afterwards.

Navigation and shell

  • 44px nav, menu and theme-toggle targets, a skip link, aria-expanded on the menu, an underline on the active page (not color alone), a global :focus-visible ring, and prefers-reduced-motion support.
  • Login: password label associated with its field, autoComplete added, icons centered.
  • Favicon (was the Vite logo) and manifest theme_color now match the teal brand.

Review feedback addressed (commits a7feb64, 3051c3c)

  • Result live region now holds only the answer; Save/export and a stable role="status" sit outside it (no duplicate announcements).
  • Tooltip: Enter/Space reopens it after Escape; 44×44 hit areas; width capped to the visual viewport.
  • Popovers inside the navbar (sync details) keep the theme focus color instead of the navbar's yellow.
  • RecoveryModal Discard buttons: removed the fixed low-contrast hover:text-red-400.

Test plan

  • npm run lint: 0 errors (the same 2 pre-existing warnings as main)
  • npm test: 2217 pass. 3 fail locally, identical to main: loginHandler.test.js and importRows.test.js need the root packages jsonwebtoken and exceljs, which aren't installed in this sandbox. They pass in CI.
  • npm run build succeeds
  • CI green on the latest head: Lint · Test · Build, Analyze (javascript), CodeQL, Vercel preview
  • Confirmed the new token test fails when an old 2.6:1 color is restored
  • Playwright on phone (390px, touch) and desktop, light and dark: 32/32 checks passing:
    • tap tooltip opens and closes, and the page never widens past the viewport
    • Enter calculates, and the results are correct ($10.71 for the base case, $13.10 with processing cost, 238.1 lbs in weight mode)
    • result visible below the sticky navbar
    • 16px inputs, 44px range buttons and menu button
    • skip link and Escape close
    • axe-core (WCAG 2.0/2.1/2.2 A and AA) clean on /, /about, /data-sources, /login and /upload in both themes
  • After review fixes: 15/15 checks (keyboard reopen, 44px targets, focus color in navbar popover, live-region scope) and 10/10 (result text stays consistent after edits, tooltip fits a simulated 2× pinch-zoom)
  • Review on a real phone with the Inter font: my screenshots used a fallback font because the sandbox can't reach Google Fonts, and a mocked /api/fish-data
  • Signed-in Save button not exercised (needs a login); reviewed by reading only

Not in this PR (details in docs/DESIGN_SYSTEM.md)

  • Offline calculator bug (pre-existing): Calculator seeds from FISH_DATA_V3, whose conversions have no from/to fields (they're derived server-side). If /api/fish-data fails, "What you have" is empty and the calculator can't be used. Needs a data-layer fix.
  • Save uses live field values (pre-existing): handleSave sends the current cost/yield/target with the earlier result, so editing a field after calculating and then saving records a mismatched calculation. Fix would reuse the snapshot the result now renders from.
  • About 8 components have error/success messages styled only for dark mode (pale text-red-300/text-green-300), which are washed out in light mode.
  • Footer.jsx and InstallPrompt.jsx aren't rendered anywhere and use tokens that no longer exist.

Make the app easier to use one-handed on a dock or mid-service, and fix
places where text was unreadable.

Readability
- Add theme-aware text tokens (accent, link, success, danger) and a
  stronger form-control border; fix text-muted. Light text-muted was
  2.6:1 and terracotta links 3.6-4.0:1; dark-mode headings that used
  text-brand-teal were ~2:1 (About, Data Sources, Community, Upload).
- Codemod text-brand-teal/-terracotta/red-500 to the new tokens.
- SyncStatusBadge used teal/gray icons on the teal navbar; use light ones.
- About CTA: white on terracotta was 4.0:1; add AA-safe brand-cta.
- designTokens.test.js enforces WCAG AA on every token pair.

Calculator
- Two numbered steps, plain-language labels, 48px controls, 16px inputs
  (no iOS focus zoom), Enter key calculates, result scrolls into view
  and is announced, disabled button explains why.
- Help tooltips now work on tap and keyboard, stay on screen, and close
  on outside tap or Escape (were hover-only, unreadable on phones).
- Labels bound to fields; "Applied to weight" shows only when a
  processing cost is entered; Sign in uses a router Link so a
  calculation is not lost to a full reload.

Navigation and shell
- 44px nav/menu/theme targets, skip link, aria-expanded, active-page
  underline, global focus ring, reduced-motion support.
- Login: associate the password label, add autocomplete, center icons.
- Favicon and manifest theme color match the current teal brand.

Add docs/DESIGN_SYSTEM.md with token rules and known follow-ups.

The update adds shared design tokens and contrast tests, adjusts styling and accessibility across application pages, and reorganizes the calculator form. It also updates application icon and theme-color metadata.

Changes

Interface and calculator updates

Layer / File(s) Summary
Theme tokens and visual foundation
app/src/index.css, app/tailwind.config.js, app/src/lib/__tests__/designTokens.test.js, docs/DESIGN_SYSTEM.md, app/index.html, app/vite.config.js
Shared theme tokens and component styles are updated. New tests check color-token presence and contrast thresholds. Documentation and application theme-color metadata are added or revised.
Application navigation and themed components
app/src/App.jsx, app/src/components/*
Navigation controls gain touch-target sizing and accessibility attributes. Login fields gain labels and autocomplete values. Application components adopt shared theme color classes; existing data and submission behavior remains unchanged.
Calculator form and results
app/src/components/Calculator.jsx
The calculator uses labeled form steps and interactive tooltips. Processing-weight options appear when a processing cost is entered. Results are announced and scrolled into view, and the acronym reference becomes a collapsible list.

- Tooltip: Enter/Space (detail === 0, incl. assistive tech) now reopens
  it after Escape; 44px hit area on icon-only help buttons and on inline
  abbreviation buttons via a pseudo-element, without shifting layout.
- Focus ring: popovers rendered inside the navbar (sync details) use the
  theme focus color instead of the navbar's yellow, which was ~1.6:1 on
  their white surface.
- Result: keep the live region mounted but scope it to the answer only;
  Save/export and a stable role="status" sit outside it, so button labels
  and save status are not announced twice.
- RecoveryModal: drop the fixed hover:text-red-400 (2.8:1 on light) from
  both Discard buttons.

- Snapshot the yield and target weight when a result is computed and
  render the description from that, so editing either afterwards can no
  longer make the live region announce an impossible combination such as
  "238.1 lbs ... makes 200 lbs".
- Cap the tooltip width to the visual viewport before positioning it, so
  pinch-zoom or high browser zoom cannot clip the right edge of the help
  text.

Resolve against the touch-first calculator (#118) and the contributor

re-add the invalid-yield message in the new layout using the danger
