Locked token sheet (do not deviate)
Every variable below is defined in the seed's :root. Slides reference tokens only — never hard-code a color in slide markup.
nexu-io/open-design
A pop-culture retrospective on how 1980s design language shaped today's apps — the scenes, the turning point, and the takeaway. Built as a decision-grade story deck for talk audience, design community.

Use for a design task while explicitly checking the source sections.
Use hps-memphis-pop for this design task: [task]. Inputs and constraints: [details]. Work through these pinned SKILL.md sections: “Locked token sheet (do not deviate)”, “Signature decor devices (the Memphis kit)”, “Layout system (shared upstream 31-layout catalog)”, “Page structure & runtime contract (keep the seed script verbatim)”, “Authoring checklist”. Cite the concrete requirements that shape each step, do not invent capabilities absent from the source, and verify the result against: [acceptance criteria].

Write and maintain DESIGN.md + PRODUCT.md — captures visual decisions and interaction patterns so design tasks stay consistent across sessions without re-scanning past work.
Use BEFORE writing or editing any non-trivial UI — inventories components, design tokens, shadcn primitives, and reusable patterns into state.ui_audit. Hard gate for the ui directive set.
A locked single-theme deck plugin: the memphis-pop skin from the upstream
MIT-licensed lewislulu/html-ppt-skill
(36 themes × 31 layouts), shipped as one self-contained seed — example.html —
that carries the full token sheet, the Memphis decor devices, the slide
scaffold, and the keyboard runtime.
Start from example.html. Replace content only. Never rewrite the design
system or the runtime script. Never introduce colors or fonts outside this
spec.
Positioning vs. sibling Memphis-adjacent plugins: this is the full-bleed
scattered confetti-dot pattern Memphis. daisy-days is hand-drawn daisy
childlike (flower illustration devices), block-frame is big-color-block
neobrutalist (no pattern). The three decor systems are mutually exclusive —
do not mix.
Every variable below is defined in the seed's :root. Slides reference
tokens only — never hard-code a color in slide markup.

body background tiles three offset
radial-gradient layers of 3px dots (pink / teal / yellow at
200 / 220 / 260px tile sizes) over --bg. It is full-bleed on every
slide; slides stay transparent so the pattern always shows through.
Never paint an opaque slide background..card is 2.5px solid #111 with
--shadow (hard offset, zero blur). Hero cards may use --shadow-lg.#111 and
filled with one accent, scattered absolutely behind/around content
(.memphis-shape). 2–4 per slide maximum..pill carries a 2px black border, an accent
fill and a slight rotate(±2deg); used as tags and badges..divider-accent is a hot-pink bar with
a black outline; section dividers pair it with a giant outlined numeral..gradient-text (the tri-color
--grad) is reserved for big numbers and 1–2 highlight words.The upstream catalog is shared across the html-ppt family; compose pages from these master categories:

external library. The seed demonstrates: cover, toc, section-divider,
two-column, kpi-grid, stat-highlight, chart-bar, process-steps, big-quote,
