-Polymodel looks like a set of well-kept engineering blueprints rendered for the web. The page is drafting paper; content sits on crisp bordered panels with near-square corners; technical metadata is set in monospace the way a drawing carries its measurements; empty media reads as a faint drafting grid awaiting geometry. The teal primary is drawing-ink blue; a single warm orange is the one action accent, used like a redline. It is a **product** surface: design serves the task of browsing, judging, downloading, and publishing printable things. The tool should disappear into the work.

+This system explicitly rejects the flat-SaaS dashboard look (rounded cards everywhere, purple/blue gradients, soft shadows, Inter-for-everything) and the reflexive dark-terminal "developer tool" aesthetic.

 ### Primary
-- **Drawing-Ink Teal** (#1f6d8a): The structural brand color — active tabs, selected state, focus rings, section emphasis, grid lines (at low alpha). Carries identity without being the action color.
+- **Drawing-Ink Blue** (`oklab(0.479428 -0.035191 -0.111636)`): The structural brand color — active tabs, selected state, focus rings, section emphasis, grid lines (at low alpha). Carries identity without being the action color.
 
 ### Secondary
-- **Slate Teal** (#5a8797): Supporting teal for secondary controls and quieter structural accents.
-- **Deep Teal** (#0f4159): High-emphasis teal for hover ink and strong labels against light surfaces.
+- **Slate Blue** (`oklab(0.613677 -0.025079 -0.065437)`): Supporting blue for secondary controls and quieter structural accents.

 ### Tertiary
-- **Redline Orange** (#c5652a): The single warm action accent — primary buttons and the one element that should pull the eye to "do this." **Action only, never decoration.**
-- **Rust Link** (#a24d1f): Inline text links, distinct from the action button so links don't read as buttons.
+- **Action Blue** (`oklab(0.516800 -0.033898 -0.129915)`): The single action accent — primary buttons and the one element that should pull the eye to "do this." **Action only, never decoration.**
+- **Link Blue** (`oklab(0.485173 -0.035448 -0.128511)`): Inline text links, distinct from the action button so links don't read as buttons.
 
 ### Neutral
-- **Drafting Paper** (#f5f1e8): The body background. A warm paper tone tinted toward the brand — the blueprint substrate, not a generic off-white.
-- **Sheet** (#fffdf7): Raised panel/card/surface background.
-- **Blueprint Overlay** (#e8edf0): Cool inset background for media wells and grid placeholders.
-- **Ink** (#17252f): Body text.
-- **Emphasis** (#0c1f2c) / **Subtle** (#445461) / **Muted** (#6a747b): The text-emphasis ramp; pick by importance, never drop body to muted-gray on the paper base.
-- **Border** (#a9b8bf): The 1px line on every panel, control, and pill.
-- **Highlight** (#d8e5e9): Selection/skeleton shimmer tint.
+- **Drafting Stock** (`oklab(0.980696 -0.001930 -0.004746)`): The body background. A cool blue-white substrate — blueprint-adjacent without drifting into warm cream or flat SaaS white.

 ### Status
-- **Error** (#a13f32) / **Warning** (#b36a16) / **Success** (#2d7358): Semantic state only, paired with shape/label, never color-alone.

 ### Named Rules
-**The One Redline Rule.** Redline Orange (#c5652a) is the action accent. It marks the single primary action in a view and nothing decorative. If two things on a screen are orange, one is wrong.
+**The One Action Rule.** Action Blue (`oklab(0.516800 -0.033898 -0.129915)`) is the action accent. It marks the single primary action in a view and nothing decorative. If two elements compete as primary action, one is wrong.
 
-**The Paper-Is-Identity Rule.** The body background is drafting paper (#f5f1e8), a deliberate tinted neutral — not the AI warm-cream default. Never rename it `--paper`/`--cream`/`--sand` and never swap it for a flat #fff/off-white; the paper tone carries the blueprint metaphor.
+**The Stock-Is-Identity Rule.** The body background is cool drafting stock (`oklab(0.980696 -0.001930 -0.004746)`), a deliberate blue-white neutral — not warm cream and not flat SaaS white. Never rename it `--paper`/`--cream`/`--sand`; the cool stock tone carries the blueprint metaphor.
 
-**The Ink-Not-Gray Rule.** Body text reaches for the ink end of the ramp. Light-gray "for elegance" on the tinted paper is the contrast trap; when a value is close to 4.5:1, move toward Ink/Emphasis, not Muted.

 ### Buttons
 - **Shape:** Near-square (2px radius); base controls render at 0px corners. Never round to pill (except deliberate tags) or 12px+.
-- **Default:** Sheet background, 1px border, ink text. Hover shifts border to teal and text to deep teal.

+- **Secondary / Ghost:** Blue border + deep-blue text (secondary); transparent background (ghost).
 
 ### Chips / Tabs / Status pills
 - **Style:** 1px border, near-square, mono text, ~0.72rem. Transparent at rest.

-- **Border:** 1px Border (#a9b8bf) — the defining line.
+- **Background:** Sheet (`oklab(1.000000 0.000000 0.000000)`) over the stock base.

 - **Shadow Strategy:** Paper hairline only (see Elevation).
 - **Internal Padding:** ~1rem; metadata rows in mono, subordinate to title/creator.
 - **Media:** Drafting-grid background (20px grid, grid-line color) for previews and placeholders — never a flat gray box; missing media draws nested registration rectangles, not fake content.
 
 ### Inputs / Fields
-- **Style:** Paper-base fill, 1px border, 2px radius, body sans.
