The native agent owner page overflows a 375px viewport to 442px when its API boundary URL is long. Actual Chromium acceptance against the mounted host and disposable PostgreSQL showed the boundary paragraph has a 285px visible box but 397px scroll width. Grant creation/reload and revocation/reload passed; the strict mobile width check correctly failed.

Allow long boundary and retained grant text to wrap using overflow-wrap:anywhere. Keep all text visible and preserve the native form, explicit permission/confirmation flow, current owner authorization, scopes and expiry. This is a one-line CSS change on the frozen owner-policy prerequisite; no credential, grant, schema, platform or deployment change.

Validation: gofmt -d and git diff --check pass. Multisite PR148 exact head 2d6bf39a4ccadb9349a7d9ec933e88518f32d9b3 consumed this exact Auth commit 05097c9d8967dc81a975f8f2b3c0764c25fe5c34. Terminal successful CMS CI run 38083999153 passed all four mandatory Chromium scenarios without skips or failures. The owner scenario passed all six checks, including create/reload, revoke/reload, contrast, visible keyboard focus and session-loss denial. Actual mobile document width is 375px at a 375px viewport, and the full boundary and retained grant text remain visible. The enclosing PostgreSQL test also passed its post-browser audit binding, current runtime guard and two store reopenings. The consumer's general build and native PostgreSQL 17/18 lanes passed; CI's dependency checksums match the committed source. No local Go/Docker/build or hosted writes performed.

This draft is stacked on Auth64 (fix/agent-owner-ui-policy-20261009) and preserves Auth63/64 unchanged. Auth workflows target main, so normal retargeting and fresh upstream exact-head CI are required after prerequisites merge, before merge/release. Consumer source CI does not waive repository protections or authorize activation. Independent source review and final successful browser artifacts are retained in the parent task at verification/multisite-reusable-agent-editing-independent-review-2d6bf39-2026-10-10.md and verification/agent-editing-2d6bf39-ci/browser/native-cms/.
