refactor(copy): start CloserCopy catalog — migrate paywall + subscription voice copy

Establishes a typed Kotlin copy catalog (ui/brand/CloserCopy.kt), sibling to the existing
CloserBrandCopy (privacy rotator). Rationale over strings.xml: the app is English-only and
pre-launch, so a typed catalog gives one-place brand-voice review + compile-time safety
without Compose stringResource() friction or orphaned-string drift. strings.xml's real value
is the localization pipeline, which we migrate to in one pass when i18n is on the roadmap
(gate recorded in Future.md).

First slice (highest-value, monetization surface):
- PaywallScreen + SubscriptionScreen voice copy (benefit lists, headlines, value props,
  "Thank you for supporting Closer", couple-shared taglines) now source from CloserCopy.
- Generic chrome ("Continue", "Restore", "Manage subscription", error-retry) intentionally
  stays inline — it isn't brand voice.
- Surfaced real copy drift: the paywall and subscription benefit lists differ (swap two
  items + reorder) — co-located and flagged in CloserCopy.kt for a copy decision, left
  verbatim (not silently unified).

compileDebugKotlin clean; no behavior change (copy identical, just relocated).

 - **Skeleton/loading states over bare spinners (P8).** `LoadingState` exists but many screens still use a bare `CircularProgressIndicator`. Add skeletons for question lists, game histories, home modules, paywall offerings, sync/reveal waits. Acceptance: no primary route shows an isolated spinner on an otherwise blank screen.
 - **Paywall / store value framing (P12).** Paywall has benefits/restore/legal/RevenueCat; needs stronger value framing, real offering/trial clarity, screenshots/previews, and test coverage before release. (Overlaps Pass K/O.)
 - **Content metadata & personalization (P13).** The bank is clean; the next leap is *routing*, not more questions — tag mood/depth/relationship-stage/conflict-safe/intimacy-level/time-needed and extend the selection APIs so prompts adapt to skipped topics, relationship length, and recent answers.
+- **Copy convention + i18n gate.** The app renders copy from hardcoded Compose literals; a half-built `strings.xml` catalog (55 unwired entries) was purged (2026-07-09), and voice copy is being centralized into typed Kotlin catalogs (`ui/brand/CloserBrandCopy.kt` = privacy rotator, `ui/brand/CloserCopy.kt` = product/paywall voice) — one reviewable home, compile-safe, no `stringResource()` friction. Convention: **voice copy → catalog; generic chrome ("Continue"/"Restore") stays inline.** Deliberately NOT localized. **Hard pre-localization gate:** the day translation is on the roadmap, migrate the Kotlin copy catalogs → `res/values/strings.xml` in one pass (retrofitting i18n across hardcoded Compose after launch is far more expensive). First slice done: paywall + subscription; remaining voice copy (onboarding, invite share, age-gate) migrates incrementally as those screens are touched. (Also surfaced: the paywall vs. subscription **benefit lists diverge** — noted in `CloserCopy.kt` for a copy decision.)
 
 ## Release / pre-ship (consolidated + re-verified 2026-06-28)
 - **Real release config before any store submission.** Confirmed still open: `app/build.gradle.kts` `versionCode = 1` / `versionName = "0.1.0"` and `core/navigation/ExternalLinks.kt` legal URLs are placeholder TODOs (`https://closer.app/privacy|terms|subscription-terms`). _Already done:_ a release-blocking Gradle check now fails the build if `RC_API_KEY` is unset/placeholder (`build.gradle.kts:106–110`), so the old "add a gradle guard" sub-item is closed. Remaining: set real version, real legal/support URLs, real RC key + verify offerings/purchase/restore on internal testing. (Tracked by **Pass O** release-readiness.)
