key-decisions:

  - "Map UI-SPEC spacing tokens 2xl and 3xl to Kotlin identifiers xxl and xxxl."
  - "Keep Material 3 imports only in RecipeTheme.kt; token files depend only on Compose UI/runtime primitives."

patterns-established:
  - "RecipeTheme exposes colors, typography, spacing, shapes, and glass through @Composable @ReadOnlyComposable getters."
  - "Theme token data classes carry locked UI-SPEC values and avoid raw Material 3 dependencies."

# Phase 02.1 Plan 02: Design Token Theme Summary

**Recipe design tokens with light/dark semantic colors, typography, spacing, chrome shape/glass defaults, and a MaterialTheme-compatible RecipeTheme provider.**

## Performance

- **Duration:** 6 min
- **Started:** 2026-05-08T12:07:58Z
- **Completed:** 2026-05-08T12:14:06Z
- **Tasks:** 2
- **Files modified:** 7

## Accomplishments

- Added five token data classes for colors, typography, spacing, shapes, and glass defaults.
- Rewrote `RecipeTheme.kt` to provide five static CompositionLocals plus `RecipeTheme.*` read-only accessors.
- Preserved the Material 3 wrapper so `LoginScreen`, `PostLoginPlaceholderScreen`, and `SplashScreen` continue using `MaterialTheme.*`.

## Task Commits

Each task was committed atomically:

1. **Task 1: Create token data classes** - `7263231` (feat)
2. **Task 2: Rewrite RecipeTheme.kt** - `6c8ca90` (feat)

**Plan metadata:** this docs commit

## Files Created/Modified

- `composeApp/src/commonMain/kotlin/dev/ulfrx/recipe/ui/theme/RecipeColors.kt` - Semantic light/dark color tokens with locked UI-SPEC hex values.
- `composeApp/src/commonMain/kotlin/dev/ulfrx/recipe/ui/theme/RecipeTypography.kt` - Display, title, body, and label text styles.
- `composeApp/src/commonMain/kotlin/dev/ulfrx/recipe/ui/theme/RecipeSpacing.kt` - xs/sm/lg/xl/xxl/xxxl spacing scale.
- `composeApp/src/commonMain/kotlin/dev/ulfrx/recipe/ui/theme/RecipeShapes.kt` - Pill/circle chrome radii.
- `composeApp/src/commonMain/kotlin/dev/ulfrx/recipe/ui/theme/RecipeGlass.kt` - Border, shadow, and blur defaults for future GlassSurface work.
- `composeApp/src/commonMain/kotlin/dev/ulfrx/recipe/ui/theme/RecipeTheme.kt` - MaterialTheme wrapper plus Recipe CompositionLocal provider.
- `.planning/phases/02.1-app-shell-navigation-search-foundation/02.1-02-SUMMARY.md` - Execution summary.

## Decisions Made

- Followed the plan's dual-theme decision: legacy auth code remains on MaterialTheme, while new shell code reads `RecipeTheme.colors`, `RecipeTheme.typography`, `RecipeTheme.spacing`, `RecipeTheme.shapes`, and `RecipeTheme.glass`.
- Used Kotlin-safe spacing identifiers `xxl` and `xxxl` for UI-SPEC `2xl` and `3xl`.
- Kept token files free of `androidx.compose.material3` imports; only `RecipeTheme.kt` imports Material 3.

## Deviations from Plan

No implementation deviations from the locked token values or theme API.

### Verification Deviations

**1. Plan command unavailable: `:composeApp:commonTest`**
- **Found during:** Plan-level verification
- **Issue:** Gradle reported that task `:composeApp:commonTest` does not exist in `:composeApp`.
- **Resolution:** Ran `:composeApp:iosSimulatorArm64Test` as the available iOS/common-source regression test task.
- **Result:** Passed.

**2. Pre-existing Spotless failures block `:composeApp:check`**
- **Found during:** Task 2 acceptance verification
- **Issue:** `:composeApp:check` fails at `spotlessKotlinCheck` in files outside this plan, including `App.kt`, `AuthSession.kt`, and `LokksmithOidcSupport.kt`.
- **Resolution:** Did not modify those files because plan ownership is limited to theme files and the user explicitly requested that dirty auth/user files remain untouched.
- **Result:** Owned theme code compiles through `:composeApp:compileKotlinIosSimulatorArm64`; no auth-screen diff was introduced.

---

**Total deviations:** 0 implementation deviations, 2 verification/environment deviations.
**Impact on plan:** Theme implementation is complete. Full `check` remains blocked by unrelated formatting debt outside this plan's ownership.

## Issues Encountered

- The plan's TDD flags could not be executed as RED/GREEN test commits without creating test files outside the plan ownership list. Verification was performed through compile and acceptance checks instead.
- Full `:composeApp:check` remains blocked by unrelated Spotless violations outside the owned files.

## TDD Gate Compliance

Warning: Task-level `tdd="true"` was present, but no test files were owned by this plan. No RED `test(02.1-02)` commit was created. The implementation was verified with the plan's compile, grep, auth-diff, and iOS simulator test checks.

## Known Stubs

None.

## Verification

- `./gradlew :composeApp:compileKotlinIosSimulatorArm64 -q` - PASS
- `./gradlew :composeApp:iosSimulatorArm64Test -q` - PASS
- `./gradlew :composeApp:commonTest -q` - NOT AVAILABLE, task does not exist
- `./gradlew :composeApp:check -q` - BLOCKED by pre-existing Spotless failures outside owned files
- No Material 3 imports in `RecipeColors.kt`, `RecipeTypography.kt`, `RecipeSpacing.kt`, `RecipeShapes.kt`, or `RecipeGlass.kt` - PASS
- `git diff --name-only composeApp/src/commonMain/kotlin/dev/ulfrx/recipe/ui/screens/auth/` - PASS, no auth screen changes

## User Setup Required

None - no external service configuration required.

## Next Phase Readiness

Plans 02.1-03 and later can consume the Recipe token API and build glass/search/dock components on top of it. The unrelated Spotless issues should be resolved by their owning wave before a full `composeApp:check` gate is required.

## Self-Check: PASSED

- Created/modified files exist on disk.
- Task commits `7263231` and `6c8ca90` exist in git history.
- `.planning/ROADMAP.md` was not modified.
- `.planning/STATE.md` remains dirty from pre-existing orchestrator/shared tracking state and was not updated by this plan.
