Using `GaEventWrapper` would include a `type: ""` key in the payload, violating design doc §0 Q5 ("OMIT type"). Direct `dataLayer.push()` with exact keys satisfies both T25 (no `type`) and the design spec. + +**HTML-parity**: The `data-ga-*` attributes are rendered directly on the button elements (as specified in design doc §8 "HTML-parity GA"), which is what `GaEventWrapper`'s Bootstrap path does anyway. + +**Risk**: No `$uds-hero-gradient-overlay` refactor was needed (§12 risk #1) — Sass import order (`_heroes.scss` before `_heroes-expandable.scss`) correctly makes the variable visible. + +### 8.2 `ExpandableHeroes.styles.js` — not created + +Design doc Appendix A lists `ExpandableHeroes.styles.js`. The component uses inline `style={{ backgroundImage: ... }}` on the button for the background image, which does not require a styled-component wrapper (unlike `Hero.styles.js` which is for the `` element). The `HeroImage` styled-component in `Hero.styles.js` applies `width: 100%` to an ``; the collapsed strip uses `background-image` on a `

Locked decisions (verbatim recap) + +All five clarifying questions are LOCKED. The implementation MUST honor every clause below; the reviewer treats deviations as P1 findings. + +- **Q1 — Interaction semantics: Option B (manual activation, APG Tabs pattern).** Hover and focus produce a **non-committing preview**. Click / Enter / Space **commit**. Arrow Left / Right / Home / End move focus among collapsed tabs **without committing**. Touch tap = commit (no hover semantics on touch). `aria-orientation="horizontal"`. **Roving tabindex.** Single active index in state. Honors `prefers-reduced-motion`. +- **Q2 — Desktop visual model: Option A (narrow vertical strips).** Active pane ~70%; each inactive pane ~15%. **These three percentages are the ONLY hardcoded numeric literals in the SCSS.** Every other value (colors, padding/gap spacing, font sizes/weights, transition durations, breakpoints, gradient) MUST come from existing Unity tokens. +- **Q3 — Rotated vertical title: same string as the expanded pane's heading.** CSS-rotated. The full string is in the DOM and is the tab's accessible name. **No separate `collapsedLabel` prop, no `aria-hidden` on visible text, no string truncation.** SCSS handles overflow via `overflow: hidden; text-overflow: ellipsis;` on a constrained inline-block tied to the parent pane's height — never alter the string itself. +- **Q4 — Desktop breakpoint: `lg` (≥992px / `$uds-breakpoint-lg`).** Use `@include media-breakpoint-up(lg)`. Below `lg`, all three panes stack vertically and render fully expanded; collapse/expand interaction does not exist below `lg`. **CSS-only gating** of layout: `role="tab"`, `role="tabpanel"`, `aria-selected`, `aria-controls`, `aria-orientation="horizontal"` are always present in the DOM at all viewports; CSS visually disables the strip layout below `lg`. **JS does NOT swap semantics on resize.** Tradeoff: an SR at narrow widths will announce a tablist on a stacked column — unusual but not incorrect, and it avoids mid-resize semantic flips. +- **Q5 — GA payload (single-fire; payload shape is locked, wiring mechanism amended in §8):** + - `event` / `data-ga-event`: `link` + - `action` / `data-ga-action`: `click` for mouse/touch commits, `keypress` for keyboard commits (Enter/Space) + - `component` / `data-ga-component`: `expandable-heroes` + - `region` / `data-ga-region`: prop (default `main content`) + - `section` / `data-ga-section`: prop (default `hero`) + - `text` / `data-ga`: the pane's title string + - `type` / `data-ga-type`: **OMIT** (state toggles, not navigation) + - Hover previews do **NOT** fire GA. + +### Hard stop-conditions for the coder + +- No PR, no push, no commits to `dev` / `master`. **Branch + Conventional Commits only.** +- Do not modify `component-header-footer` token assumptions (out of scope). +- Do not hardcode colors / spacing / fonts / breakpoints / transitions. **Only the three width percentages (70% / 15% / 15%) are exempt.** +- Reviewer + acp-visual will validate. Every assertion in the §10 test matrix must trace back to a section above. + +--- + +## 1. Problem statement + success criteria (office-hours) + +### Problem +The Unity design system needs a hero-class composition that presents **exactly three** narratives side-by-side at desktop widths, where one is expanded as a full hero and the other two remain visible as narrow, clickable "strips" with their title rotated 90°. Users can preview a strip by hovering/focusing and commit to expand by clicking, tapping, or pressing Enter/Space. At narrow widths the three panes stack and the collapse/expand interaction is suspended. + +Today this composition does not exist in `unity-react-core` or `unity-bootstrap-theme`. Building it on top of the existing `Hero` component preserves visual parity with the established hero treatment and reuses the existing Unity tokens. + +### Success criteria + +1. **Functional:** The component renders three panes; the active pane composes the existing ``; the inactive panes render a rotated title strip whose visible text equals the pane's heading text. +2. **Interaction (APG Tabs, manual activation):** Hover/focus = preview (visual emphasis, no state change). Click / Enter / Space / touch tap = commit. Arrow Left/Right/Home/End move roving focus without committing. Honors `prefers-reduced-motion`. +3. **A11y:** Full `tablist` / `tab` / `tabpanel` semantics with `aria-orientation="horizontal"`, `aria-selected`, `aria-controls`. Roving tabindex. Visible focus ring. Body text contrast ≥4.5:1; large/title contrast ≥3:1. Reflow works at 320px. Forced-colors mode legible. Component passes axe with zero violations. +4. **Brand / Tokens:** Every color, spacing, font-size, font-weight, breakpoint, transition duration, and gradient resolves to a `$uds-*` token from `_custom-asu-variables.scss` or a mixin defined in `_heroes.scss`. The only hardcoded numeric literals are the three pane widths (70% / 15% / 15%). +5. **HTML parity:** A pure-HTML story variant renders the exact same DOM tree as the React component (modulo content swaps), so CMS authors can copy-paste markup with identical CSS hooks. +6. **GA:** A single `dataLayer.push()` per commit with the payload defined in Q5 above. Hover does not fire GA. +7. **Build/lint/tests:** `yarn build`, `yarn lint`, vitest unit suite, and `run-story-tests` (interaction + a11y) all pass. + +### Out-of-scope (handled in §12) +- N≠3 panes, programmatic "open all", auto-rotation/carousel behavior, deep-link via URL, animated image transitions on commit, RTL layout, vertical orientation, custom collapsed-label strings, sub-tab nesting. + +--- + +## 2.

The collapsed strips render their own minimal markup (image + rotated title) — they do NOT render ``. This keeps the collapsed-strip DOM cheap. + +#### Type file + +A new typedef file is added at `packages/unity-react-core/src/core/types/expandable-heroes-types.js` exporting the `ExpandableHeroPane` and `ExpandableHeroesProps` typedefs and a JSDOC sentinel, mirroring `hero-types.js`. + +--- + +## 4.

The keyboard / pointer handlers remain attached — pressing Enter on a tab still updates `activeIndex` and still fires GA, but no visual layout change occurs because every pane is already expanded; this is acceptable because the SR experience remains consistent. + +``` + ┌────────────────┐ + │ IDLE │◀────────────────────────┐ + │ activeIndex=A │ │ + └─┬──────┬────┬──┘ │ + │ │ │ │ + pointerenter(i≠A) │ │ │ focus(i≠A) │ + focusin(i≠A) │ │ │ │ + ▼ │ │ │ + ┌─────────────────────┐ │ + │ PREVIEWING(i) │ │ + │ activeIndex=A │ │ + └─┬─────┬─────┬───────┘ │ + │ │ │ │ + leave/blur │ │ │ ArrowL/R, Home, End │ + ─────────────┘ │ ▼ │ + │ moveFocus(i') ─────────── (focusIndex│ + │ ▶ PREVIEWING(i') changes, │ + │ activeIndex│ + │ unchanged) │ + │ │ + commit (click / │ │ + Enter / Space / ▼ │ + touch tap) ┌──────────────────────┐ │ + │ COMMITTED(i) │ ── side effects ──▶│ + │ activeIndex ← i │ GA event │ + │ previewIndex ← null │ onPaneChange(...)│ + └──────────┬────────────┘ │ + │ │ + └────── transitions to IDLE ─────▶ +``` + +### Touch path +- Hover semantics are suppressed on touch by detecting `pointerType === 'touch'` in `onPointerDown` and short-circuiting the preview state set.

A11y contract + +### Semantics + +| DOM node | Role | Required ARIA | Notes | +|---|---|---|---| +| Root container | `tablist` | `aria-orientation="horizontal"`, `aria-label` (configurable, default "Expandable hero panes") | Always present, all viewports. | +| Each tab button | `tab` | `aria-selected={i === activeIndex}`, `aria-controls={panelId}`, `id={tabId}`, `tabindex={i === focusIndex ? 0 : -1}` | Roving tabindex. Tab IS the strip element (acts as both interactive trigger and the visible strip surface). | +| Each panel | `tabpanel` | `aria-labelledby={tabId}`, `id={panelId}`, `tabindex="0"` (only when active, to make focusable for users tabbing past) | Inactive panels: rendered in DOM with `hidden` attribute below `lg`-stack mode; above `lg`, inactive panels are NOT rendered (the strip itself is the visible representation). To keep the DOM consistent both ways, the chosen model is: at `≥ lg`, only the active pane renders `` content; the collapsed strips do not. The tab still owns the rotated label and is its own accessible name. SRs in collapsed state will hear "Tab, [title], 1 of 3, not selected" — correct APG behavior. | + +### Keyboard map + +| Key | When focus is on a tab | Effect | +|---|---|---| +| `Tab` | Tab focused | Moves focus out of the tablist (focus goes to next focusable region per browser order). | +| `Shift+Tab` | Tab focused | Moves focus out of the tablist (previous focusable region). | +| `ArrowRight` | Tab focused | Move focus to next tab (wraps from last to first). **No commit.** | +| `ArrowLeft` | Tab focused | Move focus to previous tab (wraps from first to last). **No commit.** | +| `Home` | Tab focused | Move focus to first tab. **No commit.** | +| `End` | Tab focused | Move focus to last tab. **No commit.** | +| `Enter` | Tab focused | **Commit** focused tab.

The tab's accessible name is computed from the visible text content (no `aria-label` override on the tab). Therefore the visible label is contained within the accessible name verbatim, satisfying SC 2.5.3. The CSS rotation does not change the text content. The `aria-label` on the surrounding tablist is the only `aria-label` in use and applies to the container, not the tabs. + +--- + +## 7.

To be explicit: the SCSS contains exactly two `%` literals in the layout rule — `15%` and `70%`.

The coder MUST verify scope; if Sass partial scoping prevents reuse, the coder will refactor `$uds-hero-gradient-overlay` upward into either `_heroes.scss`'s top (so subsequent imports see it) or duplicate the literal — **and if duplicating, this is the lone exception requiring architect re-approval.** Preferred path: declare `_heroes-expandable.scss` to be imported AFTER `_heroes.scss` (already specified in the import order above), and Sass `@import` makes the variable visible to subsequent partials in the same compilation unit, so reuse should work without refactoring. + +--- + +## 8.
