[design-qa][P1] Focus and tap targets: fields that never take focus, controls at 20–36 dp

[cestercian]

Part of the Sep-2026 designer's-eye QA of the 138 "Artistant iOS Light" screens (theme T15, category slow; epic #161). Full report with evidence and per-screen coverage: docs/DESIGN_QA_2026-09.md; the per-section appendices under docs/design-qa/ carry the code excerpts.

Why it matters. Enter code, email, handle, search, feedback and the counter sheet all open with their only field unfocused; inline text actions are ~36 dp, the sheet header action 40 dp, wizard text buttons 33 dp, and the search bar / chip / segment cores 36, 36 and 20 dp.

Fix direction. FocusRequester on entry for single-field screens; minimumInteractiveComponentSize() or size.rowMin on every small control.

Findings (9: P1 ×1, P2 ×7, P3 ×1)

• F-GS-09 (P2) — Enter code (and the email/handle forms) never request focus on entry
  • Screens: 119, 28, 29
  • Where: feature/signup/EnterCodeScreen.kt:119-126; feature/signup/EmailSignUpScreen.kt:154-165; feature/signup/ProfileScreen.kt:144-160; designsystem/component/OtpField.kt and designsystem/component/AppTextField.kt contain no FocusRequester
  • Fix: Add an autoFocus: Boolean (or focusRequester) parameter to OtpField/AppTextField with LaunchedEffect(Unit) { requester.requestFocus() }, and set it on 119's field, 28's Name and 29's Handle.
• F-GS-10 (P2) — Inline text actions have ~36 dp tap targets
  • Screens: 119, 28, 118
  • Where: feature/signup/SignupChrome.kt:353-361; call sites feature/signup/EnterCodeScreen.kt:147, :160, :184; feature/signup/EmailSignUpScreen.kt:120, :195, :260; feature/signup/WelcomeScreen.kt:101-112
  • Fix: Add .defaultMinSize(minHeight = dimens.size.rowMin) (or minimumInteractiveComponentSize()) inside InlineLink and on Welcome's login text.
• F-DS-02 (P2) — Search field never requests focus on entry
  • Screens: 14
  • Where: feature/search/SearchScreen.kt:106, :323; no requestFocus anywhere in feature/search/, feature/discover/ or designsystem/component/SearchBar.kt
  • Fix: LaunchedEffect(Unit) { if (!state.hasActiveQuery) focusRequester.requestFocus() } (skip when a Discover seed arrives, which already sets editing = false at :112).
• F-DS-21 (P3) — Sheet header's text action is a 40dp box with no overflow handling and no touch target
  • Screens: 15, 104, 53
  • Where: feature/search/SearchFilterSheet.kt:487-495 (shared with CompareByServiceSheet.kt:88-94)
  • Fix: widthIn(min = iconCircleSm) + minimumInteractiveComponentSize() (or a row of the close circle's height); centre the title against measured widths.
• F-MS-12 (P2) — The counter-quote sheet's only field does not take focus
  • Screens: 08
  • Where: feature/messages/ChatQuoteCard.kt:200-217
  • Fix: a FocusRequester with LaunchedEffect(Unit) { focus.requestFocus() } on the amount field.
• F-BN-09 (P2) — Tertiary actions are bare Texts at 20–40 dp
  • Screens: 89, 52, 20, 96
  • Where: feature/bookings/BookingsScreen.kt:563-581; feature/booking/BookingDetailScreen.kt:1175-1185, :949-959; feature/booking/ReviewSheet.kt:335-345
  • Fix: give each a heightIn(min = dimens.size.rowMin) (or wrap the nudge's Close in a 40 dp IconCircle, which the header two lines up already uses).
• F-WZ-02 (P2) — Text-only buttons are 33dp tall; eight of them on the Preview step
  • Screens: 45, 72, 39, 41
  • Where: feature/wizard/WizardPublishSteps.kt:236-256; WizardScreen.kt:364-380; WizardFormSteps.kt:485-497; WizardMediaSteps.kt:276-285
  • Fix: give these a defaultMinSize(minHeight = dimens.size.rowMin) (or route them through a shared TextAction composable that does), rather than padding a caption.
• F-SH-08 (P2) — Send feedback opens with the keyboard down and its only field unfocused
  • Screens: 64
  • Where: feature/system/FeedbackScreen.kt:150-157, :238-287
  • Fix: add a FocusRequester on the BasicTextField and LaunchedEffect(Unit) { requestFocus() }.
• F-DSYS-06 (P1) — The three most-tapped small controls are 36, 36 and 20dp
  • Screens: —
  • Where: designsystem/component/Chip.kt:87-90; designsystem/component/SegmentedControl.kt:101; designsystem/component/SearchBar.kt:88-91
  • Fix: wrap each in Modifier.sizeIn(minHeight = dimens.size.rowMin) (and minWidth for the clear glyph) outside the clip, exactly as SectionHeader.kt:68 does — the visible chip stays 36, the target becomes 44.

Acceptance

• Every finding above is closed on the cited lines (or refuted in a comment with the reason).
• ./gradlew :app:assembleDebug, :app:testDebugUnitTest and :app:lintDevDebug green.
• The screens listed above walked on the artistant AVD with the debug harness (RELEASE.md §10) and the fix confirmed visually — this audit was code-grounded, not device-walked.
