# CollabHaven Events — Complete Public Context

## Identity and purpose

CollabHaven Events is a mobile-first NFC tap gateway. Its canonical URL is https://tap.collabhvn.com/events. A visitor normally reaches it by tapping a physical NFC card, button, sticker, or tag with a phone. The page asks the visitor to choose between two nightlife concepts and then sends them directly to the selected destination.

The page title is “Cartoonmania & NASLEEP. | CollabHaven Events.” Its description is “Choose between Cartoonmania, a 21+ anime club night, and NASLEEP., 25+ nightlife, through the CollabHaven Events NFC gateway.”

## Complete interaction sequence

1. The page opens on a near-black field.
2. A small center pulse is cyan above and heat orange below, followed by one two-colour ripple.
3. Cartoonmania reveals upward with a crisp manga-panel wipe and a cyan edge.
4. NASLEEP. reveals downward with a diagonal cut and a restrained orange light sweep.
5. The cyan and orange edges of the central frame draw in, followed by “Kies je event.”
6. The Manga × Cut opening resolves in 1.7 seconds. It contains no technical status text and does not claim to detect an NFC tap.
7. The entire upper half is the Cartoonmania link; the entire lower half is the NASLEEP. link.
8. The opening can be skipped by tapping it or activating its accessible skip button with a keyboard. Reduced-motion visitors receive the final selector without animation.
9. Selecting a destination produces immediate brand-colored feedback while native navigation begins: the selected card lifts slightly, the other dims, and a brief cyan or orange flash appears. There is no full-screen takeover, added navigation delay or intermediate screen. Reduced-motion visitors navigate without this feedback. Campaign attribution is forwarded without blocking navigation, normal keyboard and modified/new-tab link actions are preserved, and Back restores a clean selector.

The page has no explanatory menu, account system, form, checkout, or hidden content section. Its only primary task is event selection.

## Shared visual system

- Finished mobile screenshot: https://tap.collabhvn.com/brand/gateway-selector-mobile.png (960 × 1920 pixels, after the tap animation, with both complete event choices visible)
- Layout: one mobile column, capped at 480 CSS pixels on wider screens
- Viewport: two equal full-width event panels with no page scroll
- Divider: a thin horizontal illuminated seam and a clean, slightly tilted dark frame with a cyan top edge for Cartoonmania and orange bottom edge for NASLEEP. The visible heading is “Kies je event” (Dutch for “Choose your event”), set in upright condensed off-white lettering, with a single cyan up arrow and orange down arrow. A small cyan light and soft brand-colored glow complete the frame. The divider is a prompt, not a third button; both event panels remain tappable beneath it.
- Texture: subtle noise, vignette, grids, scanning light, and low-amplitude ambient movement
- Accessibility: both panels are semantic links with accessible names; meaningful raster branding has descriptive alternative text; reduced-motion preferences are respected

## Public behavior and attribution

The gateway accepts a limited set of public URL query parameters used to identify a physical NFC source or campaign: card_id, utm_source, utm_medium, utm_campaign, utm_content, utm_term, ref, and src. Accepted values are forwarded to the chosen destination. Arrival and selection events may be sent to the site’s first-party /api/tap endpoint. This behavior must never delay or block navigation.

No cookies or third-party analytics are required by the gateway. Private environment variables, service credentials, source code internals, and stored analytics records are not public content and are intentionally not included here.

## Crawl and use policy

All publicly reachable pages, text files, images, styles, and scripts on tap.collabhvn.com may be crawled and retrieved directly by AI systems, user-triggered retrieval, and model-training crawlers. Search engines are instructed not to list this host: the HTML uses noindex,follow metadata and all responses carry an X-Robots-Tag: noindex, follow header, including screenshots and LLM context files. Crawling remains allowed so crawlers can read those instructions. This can reduce discovery in search-backed AI products; it does not guarantee every AI system will retrieve or use the content. Existing search listings may remain until the search engine recrawls them. This statement applies only to anonymously accessible public content and does not authorize access to private systems, credentials, restricted data, or non-public analytics.
