chore(omo): vendor impeccable skill 4.6.0

Re-copy .opencode/skills/impeccable from upstream tag skill-v4.6.0
(8a0e198, engine 0.1.15), keep LICENSE, and re-apply the OmO path
rewrite and the critique routing line.

The documented rewrite missed the base-directory fallback in SKILL.md,
which ends at scripts rather than scripts/impeccable, so the upgrade
command now rewrites the scripts directory prefix. The skills README
also notes that the engine binary is downloaded by scripts/VERSION
rather than vendored.

 # Visualize: Direction Comps & Asset Production

 ## Generate three compositional options
 
-The comp round runs inside the build's phase state: `impeccable build-phase start --direction <seed key> --kind <...>` has already run (the roll's output names the command) and its `comps` phase is open before the first comp is generated; a comp rendered before that sits outside the state, and a session resumed from that point has no phases to follow. `impeccable generate-image` refuses to write under `.impeccable/mocks/` until start has run; a harness-native image tool is bound by the same order.
+The comp round runs inside the build's phase state: `impeccable build-phase start --direction <seed reference>` has already run (with `--decision-comp <path>` when the chosen card has a decision comp) and its `comps` phase is open before the first comp is generated; a comp rendered before that sits outside the state, and a session resumed from that point has no phases to follow. `impeccable generate-image` refuses to write under `.impeccable/mocks/` until start has run; a harness-native image tool is bound by the same order.
 
-Render three distinct high-fidelity north-star comps of the requested surface, saved under `.impeccable/mocks/` so they survive the session. Comp at the surface's own viewport: portrait at device size for a native app or mobile-first surface, desktop landscape otherwise; a phone screen comped landscape misstates the composition before anything is built against it. Comps are the build thread's own work, never delegated: the thread that writes the prompts holds the direction's full context and has seen every comp when the build starts. Open every image by its workspace-relative path; sandboxed viewers reject absolute paths, and everything under the project root has a relative one. Base the comps on real content and the surface concepts already developed with the user. On an established world, anchor every comp on the real identity: capture a screenshot of a representative existing page and pass it as a reference image (the harness image tool's input image, or `impeccable generate-image --ref`); the prompt leads with the new surface's structure while the reference carries palette, type, and component character, because DESIGN.md words alone drift where a pixel reference does not. Name what the reference contributes and what it must not: chrome, palette, type, and component character carry over; the reference page's own content does not, and a banner, hero, or card lifted verbatim is the reference leaking, not fidelity. Three is the number: one comp invites rubber-stamping; the spread between three surfaces the composition worth building. The chosen card's decision comp is the first of the three: it already renders this direction at full fidelity under this discipline, so generate two more that vary what the first held fixed, and send all three to the approval point together. Only a round arriving with no decision comp (a degraded roll, an identity-mode page, a direction pinned without the decision round) renders all three here.
+Render three distinct high-fidelity north-star comps of the requested surface, saved under `.impeccable/mocks/` so they survive the session. When the chosen card has a decision comp, it is option one: it stays at its path under `.impeccable/mocks/decision/`, where the gate counts it through `--decision-comp`, and is never regenerated; render the other two.

The chosen card's decision comp is the first of the three: it already renders this direction at full fidelity under this discipline, so generate two more that vary what the first held fixed, from the direction in words rather than with the first comp as an input image (a reference image anchors the layout, and three comps collapse into one composition). How comps two and three vary from the first is the mode's call, in its COMPS rules. A variant that simplifies the first into a tidier version of itself adds no choice to the round. Send all three to the approval point together. Only a round arriving with no decision comp (a degraded roll, an identity-mode page, a direction pinned without the decision round) renders all three here.
 
-- A comp is a designed surface, not a picture of the subject. Lead the prompt with the surface's own structure: the regions this design has, named in order with their scale relationships; a page with no navigation says so instead of inventing one, and an unconventional surface states its unconventional skeleton. A prompt that leads with atmosphere gets a vignette back: the model paints the fish market instead of the fish market's website. Self-check every render: if it could hang as a poster, or reads as a photograph with some text on it, it is not a comp; regenerate with the layout scaffold stated more literally.
-- The inverse is also a failure: a surface with none of its subject in it. The subject appears as the content the regions hold; the world dresses the frame and never displaces what the frame shows. The deletion usually rides in on the prompt's exclusion list, so exclusions bind invented claims, and a medium ban belongs to the committed imagery stance, never to caution. Before accepting a render, point at the subject; a render that depicts everything about the world and nothing of the subject fails however faithful its atmosphere. Regenerate with the subject's content named region by region.
+- A comp prompt is short, 150 to 300 words, and carries only what the image model cannot know. The model draws what the prompt names and stops deciding whatever the prompt pins down, so a prompt that specifies everything gets back a template. Open with the surface: the kind of screen it is (a desktop web app, a documentation page, a landing page, a native app screen at its device viewport) for the product, by name, rendered edge to edge with crisp readable text and no browser window, device, or desk around it. Then the product and the visitor's job in plain words, with the real content that answers it: names, numbers with units, the offer or the state, any claim at its honest certainty, and the next action by name. Then what leads this comp, its product concept (summary-led, timeline-led, offer-led, reference-led), and the parts the screen holds in reading order, a phrase each. Then the frame in one line: the product's mark and name, its navigation, its utility controls, and the far edge, so the comp is a finished screen, never a fragment; a page with no navigation says so instead of inventing one. Leave sizes, positions, colours, and component styling out, except a colour, typeface, or brand element the user pinned: that is content, so state it. Self-check every render: if it could hang as a poster, or reads as a photograph with some text on it, it is not a comp; regenerate.
+- The look comes from the world, and from a picture wherever one exists. An established world has the screenshot reference above: it carries the look, so the prompt adds one sentence on what the reference contributes and nothing more about style. A catalog world has card images: attach its board and hero as reference images (the NEXT line names them; `impeccable generate-image --ref <board> --ref <hero>`, or the harness image tool's input images) and write one sentence, that the references are style inspiration adapted into a real working product, their layout and content not to be copied. Describing the style as well overrides the picture. A direction with no card images carries its look in two to four sentences of concrete visual law: the ground and main colours with what each does, the type voices, and the one signature that makes it recognisable. No path lists colours past the main few or describes components one by one.
+- The subject must be in it. Before accepting a render, point at the subject: a render that depicts the world and nothing of the subject fails however faithful its atmosphere, and the deletion usually rides in on an exclusion list. Regenerate with the subject's content named.
 - Judge a comp as the shipped screen: the visitor's job must be readable from the image alone. Name the surface's mode from the render with no caption; a render whose mode cannot be read back is art direction without a surface. Regenerate with the visitor's job as the prompt's spine.
-- Commitment is depth, not coverage. The world enters through one dominant move plus the material, type, and spacing that support it; the remaining regions hold still so that move can be read. A region that simply does its job in the world's grammar carries the direction further than a region performing the concept. The check cuts competition, never content: a quieted region keeps its information and stops performing. A second element competing with the named focal moment at the same scale means the comp is shouting; with no named focal moment, several regions performing the concept at once is the same shout. Regenerate keeping the strongest move and quieting the rest. Busy is louder, not bolder.
+- Commitment is depth, not performance spread across regions. The world enters through one dominant move plus the material, type, and spacing that support it; the remaining regions hold still in that material and keep their content at real reading size. A second element competing with the lead at the same scale is the comp shouting: regenerate keeping the strongest move and quieting the rest. Busy is louder, not bolder.
 - When the user shortlisted multiple concepts, spread the three across them.
-- When one direction is committed, vary the structural uncertainty an image can resolve: topology, sequence, density, hierarchy, focal composition, or interaction framing.
+- When one direction is committed, vary the structural uncertainty an image can resolve: what leads the screen, topology, sequence, density, hierarchy, focal composition, or interaction framing.
 - Show enough beyond the opening moment to prove the concept can govern the whole surface.
 - Do not generate a palette artifact, ask new atmosphere questions, introduce a different type voice, or invent a new motif. If the committed world cannot support the concept, return to the concept shortlist rather than changing the world.
