 ## Content and actions
 
 - Twenty Thariq HTML references, grouped by the nine source categories and linked to the original live files, each paired with an Effective SVG subject in locally served static and animated versions.
-- Six native Effective HTML artifacts: the featured architecture request-path explorer, two release-readiness studies, and three standalone product-interface studies.
+- Twelve first-party Effective HTML artifacts: the featured architecture request-path explorer, two release-readiness studies, three new wireframe-and-mockup pairs, and three standalone product-interface studies.
 - The featured explorer is the interactive diagram from the Effective HTML README. Its live HTML is the source artifact; a 30.5-second recording, poster, and four-flow animated SVG are supporting previews of the same work, not additional catalog entries.
 - The standalone studies are a Linear-like issue workspace, a Notion-like connected project document, and a Vercel-like deployment ledger. All three use synthetic data, are explicitly unaffiliated, and make no commercial product claims or use product logos.
-- The five Effective HTML skills as the methods behind the catalog.
-- Thirty-one catalog entries total: twenty HTML + SVG pairs, six native examples, and five skills. The collection is intentionally too small to justify free-text search or intersecting taxonomies, so discovery uses the nine-subject guide plus one Collection control: All, References, Hi-fi mockups, or Skills. Hi-fi mockups is the direct showcase path to the Linear-like, Notion-like, and Vercel-like studies; primary actions are Open HTML, Static SVG, and Animated SVG.
-- One global SVG Preview control switches all twenty paired SVG previews together. Preview defaults to Animated, and individual specimen cards do not carry their own animation toggles.
+- The three new pairs cover an Effective HTML catalog decision, a Plannotator review workspace, and a product-change review. Each pair keeps the system and decision fixed while moving from a rough wireframe to a product-specific mockup.
+- The six Effective HTML skills as the methods behind the catalog.
+- Thirty-eight catalog entries total: twenty HTML + SVG references, twelve first-party artifacts, and six skills. The collection is intentionally too small to justify free-text search or intersecting taxonomies, so discovery uses the nine-subject guide plus one Collection control: All, References, Wireframes & mockups, or Skills. Wireframes & mockups is the direct showcase path to ten practical design artifacts.
+- One global Preview control switches the twenty paired references and six new design artifacts between static and animated SVGs. Preview defaults to Animated; first-party entries without SVG media keep their screenshot, and individual cards do not carry their own animation toggles.
 - Expanded and Compact are two presentations of this same filtered collection. Switching modes must preserve every result, preview state, source link, and action rather than routing to a second catalog.

+- **Effective HTML catalog:** three low-fidelity browsing directions lead into a branded comparison mockup that can switch its artifact previews between desktop and mobile widths.
+- **Plannotator review:** a grayscale canvas/comments/queue wireframe leads into a dark product-aligned review workspace with width switching, annotation selection, and send feedback.
+- **Product change review:** a rough current/proposed/states comparison leads into a vivid decision artifact with current, proposed, compare, and mobile modes.

 ## Responsive constraints
 
 Desktop Expanded may stagger two or three sheets within a band; Compact uses contained shelves with a category rail and concise specimen grid. At every desktop and large-tablet width, the hero title and each expanded category heading retain reserved, non-overlapping rails. Explicit regression checkpoints are 1033px, 1375px, and 1728px, plus adjacent widths where the layout changes. Tablet reduces each expanded band to a label rail plus one or two columns.
 
 On mobile, the nine-subject guide remains before the artifact folio so the visitor sees the catalog map first. Expanded becomes a vertical sequence with full-width previews and persistent readable actions. Compact keeps each colored category band contained and lets its specimen shelf scroll horizontally inside the band; the document itself must remain overflow-free. The featured explorer stacks copy, video, and animated synopsis in that order. Reduced-motion preferences disable the view-change animation at every breakpoint.
 
-The three product-interface studies are verified at 1440×900 and 390×844. At both sizes they have no document-level horizontal overflow and keep the unaffiliated synthetic-data disclosure visible. Linear and Notion expose complete tab semantics with roving focus plus Arrow Left, Arrow Right, Home, and End keyboard behavior; all studies preserve keyboard access, visible focus, and reduced-motion support.

+# Wireframes and mockups
+
+Six standalone HTML artifacts built to show how an agent can use real product
+context instead of applying a generic interface style.
+
+## Effective HTML comparison
+
+- `effective-html-compare-wireframe.html` tests three structures for comparing
+  two live artifacts: split, stacked, and focused review.
+- `effective-html-compare-mockup.html` applies the Effective HTML Working Atlas
+  system to the selected split comparison.
+- Source context: `site/DESIGN.md`, `site/PRODUCT.md`, the current catalog, and
+  the existing same-origin artifacts.
+- Skill use: `html-wireframe` for the structural directions, then
+  `design-artifact` with `html-prototype` in mockup mode for the finished view.
+
+## Plannotator review workspace
+
+- `plannotator-review-wireframe.html` tests canvas-first, comments-first, and
+  review-queue structures for annotating rendered HTML.
+- `plannotator-review-mockup.html` follows Plannotator's current dark review
+  surface, annotation rail, selected-comment treatment, and send-feedback
+  action.
+- Source context: the public Plannotator repository, current HTML annotation
+  and code-review screenshots, and the review UI components.
+- Skill use: `html-wireframe` for the structure, then `design-artifact` with
+  `html-prototype` in mockup mode for system alignment.
+
+## Product change review
+
+- `product-change-review-wireframe.html` compares current and proposed member
+  role behavior across direct comparison, states, and mobile views.
+- `product-change-review-mockup.html` turns the same synthetic brief into a
+  polished review artifact. It is not a production product or a product claim.
+- Source context: a bounded synthetic brief about moving role actions out of an
+  overflow menu and showing permission limits before submission.
+- Skill use: `html-wireframe` for the evidence layout, then `design-artifact`
+  with `html-prototype` in mockup mode for the finished review surface.
+
+Every artifact is self-contained and requires no network connection or build
+step. Catalog screenshots and static and animated SVG previews sit beside these
+files.

+      THESIS: Plannotator review keeps the rendered artifact central while comments remain immediately actionable.
+      OWN-WORLD: Dense midnight review shell, muted blue-gray panels, purple selection, amber annotations, and green completion.
+      STORY: Inspect the rendered HTML, select the highlighted annotation, and send concise feedback to the agent.
+      FIRST VIEWPORT: A full browser review workspace with narrow tools, dominant artifact canvas, and compact annotation rail.
+      FORM: System-aligned Plannotator mockup based on the current review surfaces; seed plannotator-review-mockup.
+      FINISH: unreviewed and undocumented is unfinished; this build ends with the finish review, the verdict, and DESIGN.md

+      OWN-WORLD: Cobalt proof field, white interface plates, orange/pink review marks, exact black rules, and synthetic member data.
+      STORY: Compare current and proposed role changes, inspect the relevant states, and record a bounded decision.
+      FIRST VIEWPORT: Saturated brief above a large dual-screen proof with numbered review notes at the edge.
+      FORM: Polished product-change mockup in a subject-specific proofing language; seed product-change-review-mockup.
+      FINISH: unreviewed and undocumented is unfinished; this build ends with the finish review, the verdict, and DESIGN.md

+      STORY: Move among direct comparison, state coverage, and mobile behavior before accepting the change.
+      FIRST VIEWPORT: Change brief and three-view control above a full-width current/proposed review board.
+      FORM: Low-fidelity review artifact with three evidence arrangements; seed product-change-review-wireframe.
+      FINISH: unreviewed and undocumented is unfinished; this build ends with the finish review, the verdict, and DESIGN.md
