sync shadcn editors shell parity

Objective: Implement the accepted sync-shadcn /editors shell parity slice: make /editors follow upstream shadcn /blocks page framing while preserving Plate editor demos and excluding the category nav, v0 actions, Browse all blocks, and Browse more editors.

Goal plan: docs/plans/2026-05-29-sync-shadcn-editors-shell-parity.md

Template: docs/plans/templates/task.md

Primary template: docs/plans/templates/task.md

Applied packs:

docs (docs/plans/templates/packs/docs.md)
browser (docs/plans/templates/packs/browser.md)

Task source:

type: accepted sync-shadcn implementation slice
id / link: docs/sync/shadcn/runs/2026-05-29-4a4dc8e-to-efdec3c-editors-blocks-style/plan.md
title: Editors page shell parity
acceptance criteria: centered upstream-style PageHeader, section-soft content band, upstream block-list spacing, Plate demos retained, rejected upstream controls absent, partial sync status updated without advancing lastSyncedCommit, focused lint/typecheck and browser proof complete.

Completion threshold:

/editors renders with the approved upstream /blocks shell rhythm.
docs/sync/shadcn/status.json records the implementation as a partial sync and leaves lastSyncedCommit unchanged.
Focused eslint, pnpm --filter www typecheck, and desktop/mobile browser proof pass.
Task closure is legal only when the source-of-truth acceptance criteria are satisfied or explicitly narrowed, required verification evidence is recorded, code-review and release-artifact gates are closed when applicable, tracker/PR sync is complete or marked N/A with reason, and node .agents/rules/autogoal/scripts/check-complete.mjs docs/plans/2026-05-29-sync-shadcn-editors-shell-parity.md passes.

Verification surface:

pnpm --filter www exec eslint 'src/app/(app)/editors/layout.tsx' 'src/app/(app)/editors/editor-description.tsx' 'src/app/(app)/editors/page.tsx' --fix
pnpm --filter www typecheck
Playwright browser proof against http://localhost:3003/editors at 1175x1239 and 390x844, with screenshots saved in the sync run folder.

Constraints:

Preserve existing user-facing behavior outside the task scope.
Prefer the durable ownership boundary over caller-by-caller patches.
Do not create PRs, comments, commits, or pushes unless the task/user/skill requires them.
Do not add broad ceremony when the task is trivial or docs-only.

Boundaries:

Source of truth: docs/sync/shadcn/runs/2026-05-29-4a4dc8e-to-efdec3c-editors-blocks-style/plan.md
Allowed edit scope: /editors route files, this goal plan, sync run plan, and docs/sync/shadcn/status.json.
Browser surface: http://localhost:3003/editors.
Tracker sync: N/A, no external issue or PR requested.
Non-goals: no PageNav/BlocksNav, no Open in v0, no Browse all blocks, no Browse more editors, no full sync baseline advancement.

Output budget strategy:

Use targeted file reads, focused eslint/typecheck output, compact browser metrics, and saved screenshots instead of broad patch dumps.

Blocked condition:

Block only if the local dev route cannot be loaded, focused checks fail for causes outside this slice after one honest retry, or browser evidence shows excluded controls still present.

Task state:

task_type: visual shell sync
task_complexity: normal
current_phase: closeout
current_phase_status: complete
next_phase: final response
goal_status: active

Current verdict:

verdict: implemented
confidence: high
next owner: user review
reason: approved slice shipped with checks and desktop/mobile browser proof

Completion rule:

Do not call update_goal(status: complete) while any required checklist item remains unchecked. If an item does not apply, check it and add N/A: <reason>.
Do not call update_goal(status: complete) until every completion threshold above is satisfied, final handoff evidence is recorded, and node .agents/rules/autogoal/scripts/check-complete.mjs docs/plans/2026-05-29-sync-shadcn-editors-shell-parity.md passes.
Do not create hook state for this goal. This file plus the active goal are the durable state.

Findings:

/editors had the old route-local container and left-aligned header rhythm.
The approved shadcn parity slice only needed page shell/list changes; Plate editor demo content stayed owned by Plate.

Decisions and tradeoffs:

Kept the Browse Editors hero action because the plan only excluded the bottom Browse more editors CTA and upstream category/action controls.
Did not touch BlockViewer; toolbar cleanup remains deferred unless the user wants that second slice.

Implementation notes:

layout.tsx now wraps children in container-wrapper flex-1 section-soft md:py-12.
editor-description.tsx now renders through shared PageHeader.
page.tsx now uses flex flex-col gap-12 md:gap-24.

Review fixes:

Added centered PageActions styling after confirming the shared component's default is left-aligned in Plate.

Error attempts:

Error / failed attempt	Count	Next different move	Resolution
Node ESM/require ambiguity in first browser script	1	Rerun script as ESM with `--input-type=module`	Browser proof passed

Verification evidence:

pnpm --filter www exec eslint 'src/app/(app)/editors/layout.tsx' 'src/app/(app)/editors/editor-description.tsx' 'src/app/(app)/editors/page.tsx' --fix passed.
pnpm --filter www typecheck passed.
Browser proof on http://localhost:3003/editors passed at 1175x1239 and 390x844.
Screenshots: docs/sync/shadcn/runs/2026-05-29-4a4dc8e-to-efdec3c-editors-blocks-style/screenshots/plate-editors-desktop-after.png and docs/sync/shadcn/runs/2026-05-29-4a4dc8e-to-efdec3c-editors-blocks-style/screenshots/plate-editors-mobile-after.png.
Browser assertions: centered PageHeader present, section-soft present, Plate demos retained, no PageNav/BlocksNav, no category nav labels, no Browse all blocks, no Open in v0, no Browse more editors, and no horizontal overflow.
Console caveat: known external Potion iframe X-Frame-Options/sandbox warnings appeared; there were no page errors or failed requests.

Reboot status:

Current and complete as of 2026-05-29: implementation, sync bookkeeping, and browser verification are done; only final handoff remains.

Open risks:

None requiring more work for this slice. Optional BlockViewer toolbar density cleanup remains deferred by the sync plan.

Final handoff contract:

PR line: N/A, no PR requested.
Issue / tracker line: N/A, no tracker.
Confidence line: high; checks and browser proof passed.
Flow table:
- Reproduced: N/A for bug repro; source plan and before screenshots already captured the visual delta.
- Verified: focused eslint/typecheck passed; desktop/mobile browser proof passed.
Browser check: /editors desktop/mobile screenshots saved; rejected controls absent.
Outcome: /editors now follows the approved shadcn /blocks shell rhythm.
Caveat: Potion iframe emits known external warnings during full-page capture.
Design:
- Chosen boundary: route shell files plus sync status/run plan.
- Why not quick patch: route-level layout owns the header/content band.
- Why not broader change: BlockViewer toolbar cleanup and full sync baseline are separate deferred slices.
Verified: focused eslint, typecheck, browser desktop/mobile.
PR body verified: N/A, no PR.

Task-style PR body contract:

Preserve any existing  block. If a changeset is part of the diff and repo policy expects auto release, include that block.
Use the accepted kitcn PR #270 visual format. The body starts with an emoji issue/tracker/fix line, for example 🐛 Fixes #123 or 🐛 Fixes ➖ N/A, then an emoji confidence line like 🟢 95-100% confidence.
Use this exact table header: | Phase | 🧪 Tests | 🌐 Browser |.
Use Reproduced and Verified rows. Mark passing proof with 🟢, repro or failing proof with 🔴, and non-applicable cells with ➖ N/A.
Use bold emoji section headings: **✅ Outcome**, **⚠️ Caveat**, **🏗️ Design**, and **🧪 Verified**.
Never include a line that links to the current PR itself. The current PR URL belongs in the final response, not in its own description.
Do not replace this with a generic Summary / Verification PR body, an adaptive prose body from a git helper skill, plain ## Outcome sections, or an unrelated generated badge footer unless the caller or repo template explicitly asks for it.
Proof is gh pr view --json body output or a concise source-backed summary of that output.

Final handoff / sync:

PR: N/A.
Issue / tracker: N/A.
Browser proof: screenshots saved in the sync run folder.
Caveats: known Potion iframe warnings only.

Timeline:

2026-05-29T13:19:16.820Z Task goal plan created.

Reboot status:

Question	Answer
Where am I?	Closeout complete after implementation and verification
Where am I going?	Final response
What is the goal?	Ship the accepted `/editors` shell parity slice and record partial sync state
What have I learned?	Route shell parity was owned by `/editors` layout/header/list files; BlockViewer cleanup remains separate
What have I done?	Patched route shell, updated sync status/run plan, ran lint/typecheck/browser proof

Open risks:

None for the accepted slice; optional toolbar density cleanup remains deferred.
