 - Call `get_guidelines(topic)` using `"web-app"` or `"mobile"` for product-design principles that apply to the screen you are editing.
 - Do NOT pull a full style guide when you are adjusting an existing composition.
 
+**Visual style for new or refreshed work:**
+- Early in the loop, also fetch one visual style with `get_guidelines(category:"style", name:"Atlas Grid", colorPalette:"Alloy Blue", roundness:"medium", elevation:"low", headings:"Inter", body:"Inter", captions:"Inter", data:"IBM Plex Mono")`; choose styles like Atlas Grid, Beacon Landing, or Console Board and palettes like Alloy Blue or Amber Field.
+- Treat the returned TokenMap as reference values only.
+- BAKE concrete values (fills, text colors, radius, font) from the style directly into nodes. Do NOT create document variables from the style, and Do NOT call `set_variables` for it — the style is reference guidance, not document state. (You may still reuse the document's own existing `$variables` per Step 4.)
+
 ### Step 4 — Read design variables
 
 Call `get_variables` to see the existing design variables and themes. Reuse them by using `$variable` references in node properties instead of hardcoding color values or sizes.

+# Atlas Grid
+
+## Identity
+Atlas Grid is a practical workspace style for dense product surfaces. It favors calm surfaces, restrained accent use, and a visible rhythm that helps repeated tools feel dependable.
+
+## Layout
+Use strong rows, measured columns, and compact grouping. Primary actions should sit close to the work area, while secondary controls stay quieter and aligned to predictable edges.
+
+## Token Map usage
+Use surface.primary for the main canvas, surface.secondary for tool rails, and surface.tertiary for grouped work zones. Accent.primary is reserved for the current selection or commit action; border.subtle separates repeated rows.
+
+## Hierarchy
+Keep headings modest, usually two to three times the body size. Let spacing, alignment, and foreground weight do more work than large type.

+# Beacon Landing
+
+## Identity
+Beacon Landing is built for a first screen that makes the offer clear without becoming decorative clutter. It has a crisp product signal, direct copy, and a controlled accent path.
+
+## Layout
+Start with one dominant message and one supporting action area. Follow with visible proof or feature content so the page does not stop at a poster-like hero.
+
+## Token Map usage
+Use surface.primary for the page, surface.secondary for proof bands, and accent.primary for the single main action. Surface.inverse can frame a short proof strip or featured metric.
+
+## Hierarchy
+The top heading can be large, but supporting labels and buttons stay compact. Later sections should step down quickly into scan-friendly headings and body text.

+
+## Identity
+Chronicle Page is an editorial system for reading, comparison, and narrative product content. It uses quiet containers, confident typography, and thin separators instead of heavy panels.
+
+## Layout
+Build pages from a clear article column, side notes, pull facts, and occasional full-width breaks. Keep media and data close to the text they explain.
+
+## Token Map usage
+Use surface.primary for long-form reading, surface.secondary for side notes, and border.subtle for section breaks. Accent.secondary is useful for links, inline markers, and short labels.
+
+## Hierarchy
+Headings carry the voice, body text carries the pace, and captions stay small but readable. Avoid stacking too many headline sizes in the same viewport.

+## Identity
+Console Board is a data-operating style for dashboards, monitoring, and review queues. It is dense, legible, and low-drama, with accents used to show state and priority.
+
+## Layout
+Use stable regions for filters, tables, summaries, and inspection. Keep cards compact, favor aligned numbers, and avoid oversized decoration that slows scanning.
+
+## Token Map usage
+Use surface.secondary for control bands, surface.tertiary for nested data groups, and foreground.muted for metadata. Accent.primary marks active filters or current state; accent.tertiary can mark neutral insight callouts.
+
+## Hierarchy
+Numbers and labels should line up cleanly. Data type, weight, and proximity should create most of the hierarchy, with headings staying short and functional.

+
+## Identity
+Modular Cards is for browse, compare, and collect workflows. It uses repeated blocks with enough structure to feel systematic and enough contrast to keep each item distinct.
+
+## Layout
+Arrange repeated items on a steady grid with consistent image, title, metadata, and action zones. Vary emphasis by size or placement rather than by inventing a new card for every item.
+
+## Token Map usage
+Use surface.secondary for cards, surface.tertiary for nested badges or media mats, and border.subtle for item boundaries. Accent.secondary works well for saved, recommended, or active states.

+
+## Token Map usage
