layered-depth
Use this plugin when the user wants a cinematic, layered-parallax architecture-studio landing page (brand 'Qelora'): fullscreen background video, a giant center brand wordmark behind a parallax sculpture slab, an animated bird video state machine, frosted-glass nav pills and bottom info panels, and a second full-viewport video section with a centered editorial headline. Invoke for 'layered depth', 'architecture studio landing', 'parallax hero with video', 'Qelora', or when the user references the Layered Depth motionsites template.
What this skill does
# Layered Depth — Architecture Studio Landing (Qelora)
Produce a cinematic, depth-layered landing page for an architecture studio called **Qelora**, built on stacked z-index layers (background video → warm overlay → animated birds → giant brand wordmark → parallax sculpture slab → frosted nav → frosted info panels) plus a second full-viewport video section with a centered editorial headline.
A complete, rendered reference implementation ships beside this skill at `example.html` — **start from it**. Copy `example.html`, then adjust copy and data; do not rewrite the CSS or invent a new visual language. The seed already encodes the exact tokens, layer stacking, parallax math, bird state machine, and 768px responsive behavior described below.
This is the authoritative build brief. Follow it exactly — the named colors, fonts, asset URLs, z-indexes, and parallax constants are locked.
## Stack
- Default output: a single self-contained HTML file (the `example.html` seed). It already includes everything inline.
- If the user explicitly asks for a **React + Vite + TypeScript + Tailwind** project, port the seed faithfully into `Hero.tsx` + `Section2.tsx` (mounted by `App.tsx` → `main.tsx` in `StrictMode`, no routing). Tailwind is used **only for base reset** (`@tailwind base/components/utilities`); every element is styled with **inline styles**, no utility classes in JSX. Dependencies are only `react`, `react-dom`, `lucide-react` (lucide is declared but the page's icons are all inline SVG and lucide is not actually rendered). Do not change the design while porting.
## Fonts (Zimula Trial — locked)
Load all three in `<head>` / `index.css`:
```
<link href="https://db.onlinewebfonts.com/c/076f8c5b3b67616658dd1e4e9bac62ec?family=Zimula+Trial+Med" rel="stylesheet">
<link href="https://db.onlinewebfonts.com/c/08d8ca53f66ab5b48659912fa0136b78?family=Zimula+Trial+Bd" rel="stylesheet">
@import url('https://db.onlinewebfonts.com/c/46024824a3dd3309c3a7f46f4f1283ba?family=Zimula+Trial+Reg');
```
- Body / default: `'Zimula Trial Med', sans-serif` (primary weight, used everywhere).
- Bold / logo / hero wordmark: `'Zimula Trial Bd', sans-serif`.
- `Reg` is imported and available but Med is the primary weight.
## Global CSS (`index.css`)
```
*, *::before, *::after { box-sizing: border-box; margin: 0; padding: 0; }

## Section 1 — Hero
Container: `position: relative; width: 100%; min-height: 100vh; overflow: visible; font-family: 'Zimula Trial Med'`.
Responsive breakpoint: `isMobile = window.innerWidth < 768`, checked on mount and resize.
Stack the layers by z-index exactly:
- **Layer 1 — Background video (z-index 0):** `<video autoplay muted loop playsinline>`, `position:absolute; inset:0; width:100%; height:100vh; object-fit:cover`, source = hero bg mp4.
- **Layer 2 — Warm overlay (z-index 1):** div, `background: rgba(235,230,218,0.12); height:100vh; pointer-events:none`.
- **Layer 3 — Bird animation system (z-index 8):** container `position:absolute; top:0; left:0; width:100%; height:100vh; pointer-events:none; aria-hidden`. Four `<video>` elements (enter, idle1, idle2, leave) toggled via `display`. Desktop: each `position:absolute; inset:0; width:100%; height:100%; object-fit:cover`. Mobile: each `position:absolute; top:50%; left:0; transform:translateY(-50%); width:100%; height:auto`. **State machine** `'enter'|'idle1'|'idle2'|'leave'|'hidden'`: on load play `enter`; `enter` ended → `idle1`; `idle1` ended → `idle2`; `idle2` ended → `idle1` (infinite loop); scroll past 10px → pause/reset enter+idles, play `leave`; scroll back below 10px → pause/reset leave, play `enter` again. Use both state and a ref to avoid stale closures in the scroll handler. Preload all four with `.load()` on mount. The `playVideo` helper sets `currentTime=0`, checks `readyState>=2`, then plays (or waits for a `canplay` event).
- **Layer 4 — Center brand text "Qelora" (z-index 5):** container fills `100vh`, flex centered, `pointer-events:none`. Text `Qelora` in `'Zimula Trial Bd'`, font-size mobile `26vw` / desktop `22vw`, `letter-spacing:-0.05em; color:#241f21; line-height:1; margin-bottom:` mobile `8vh` / desktop `12vh`.
- **Layer 5 — Sculpture slab (z-index 5):** `<img>` `position:absolute; top:50%; left:50%`, `transform: translateX(-50%) translateY(${-heroScroll * 0.3}px)` — parallax that moves **UP** as the user scrolls down. Width mobile `220vw` / desktop `160vw`; `height:auto; pointer-events:none; will-change:transform`.
- **Layer 6 — Fixed navbar (z-index 100):** `position:fixed; top:0`, full width, padding mobile `16px 20px` / desktop `20px 36px`. Left: brand "Qelora" with `®` superscript (`'Zimula Trial Bd'`, size mobile `20px`/desktop `24px`, `letter-spacing:-0.03em; color:#241f21`; the `®` sup is `font-size:0.4em; vertical-align:super`). Right desktop: **NavPills** — pills for `['Projects','Studio','Responsibility','Archive']` plus an `EN` language selector. Each pill: `background:rgba(248,245,240,0.92); border-radius:12px; padding:13px 22px 8px; height:40px; font-size:13px; text-transform:uppercase; letter-spacing:0.07em; color:#241f21`. Active pill: `font-weight:700` + a 3px round dot at `bottom:3px`, centered; non-active `font-weight:500`. Default active = "Projects". Language pill: separate capsule `border-radius:100px; padding:8px 14px; background:rgba(248,245,240,0.88); backdrop-filter:blur(12px); box-shadow:0 2px 20px rgba(0,0,0,0.1)`, "EN" + chevron-down SVG. Right mobile: hamburger button `42×42; border-radius:100px`, same frosted style — X icon when open, 3-line hamburger when closed.
- **Layer 7 — Mobile dropdown menu (z-index 99):** `position:fixed; top:70px; left:16px; right:16px; background:rgba(248,245,240,0.96); backdrop-filter:blur(16px); border-radius:18px; padding:8px; box-shadow:0 8px 40px rgba(0,0,0,0.14)`. Each item: full-width button `padding:14px 20px; font-size:13px; uppercase; letter-spacing:0.07em; border-bottom:1px solid rgba(40,36,37,0.08)`. BottoRelated in Ads & Marketing

brand-library-architect
IncludedBuild a complete brand library for a product — visual asset render pipeline, brand documentation set (BRAND, COPY, MANIFESTO, BIOS, FAQ, GLOSSARY, TONE, PRICING), open-source convention files (README, CONTRIBUTING, SECURITY, CODE_OF_CONDUCT), and a self-contained press kit. This skill should be used when the user asks to "build a brand library / brand kit / press kit / brand assets" for a product, "set up a brand library workflow," "create a positioning manifesto plus visual identity," or any combination of brand documentation + visual asset pipeline. Apply phase-by-phase or run end-to-end. Templates are product-agnostic and use {{TOKEN}} placeholders the skill prompts the user to fill.
writing-tech-post
IncludedAuthors engineering blog posts end-to-end: launch deep-dives, incident postmortems, architecture migrations, performance case studies, tutorials, AI/agent system writeups, security disclosures, and research-to-product translations. Picks the correct archetype, plans the abstraction ladder, enforces an evidence cadence (diagrams, benchmarks, profiles, traces, code, ablations), tunes voice against publisher house styles (Datadog, Vercel, GitHub, AWS, Meta, Cloudflare, Jane Street), and runs a pre-publish gate for narrative momentum and disclosure ethics. Use when drafting a new engineering post, restructuring a draft that feels flat, deciding which evidence form belongs where, validating that depth and product context are balanced, or preparing a postmortem, migration, or performance narrative for external publication. Do not use for API reference documentation, README authoring, marketing copy, release notes, generic SEO content, ghost-written executive thought leadership, or non-engineering long-form essays.
