Noir is a flagship theme for CS-Cart and Multi-Vendor 4.17.2 to 4.21.x, a child of Responsive, so every add-on keeps working. It is dark by default. The homepage opens with a product stage: the products you pick in the Block Manager appear one by one in a beam of light, with name, spec chips and price. Cards, category tiles and promos catch a soft spotlight under the pointer. Five dark schemes, three Noir Light schemes, wide Syne display type and three home layouts: Stage, Gallery and Market.
One design, five dark and three light schemes
Noir is one design, dark by default. Each scheme sets its ground and one accent light as Theme Editor colours. Open any of them in the live demo.
High-ticket products get the attention they need: one product at a time on the stage, two key specs as chips on every card, the price in a light ring on the product page. Search with categories, mega menu, sticky glass header, a bottom bar, filter sheet and sticky buy bar on phones. Deal timers count down to the real end of your promotions. Every scheme keeps text contrast at 4.5:1 or more; no visitor data in the page, so it is safe for the 4.21 full page cache.
How it works
Install the zip in Add-ons, activate Noir in Website > Themes and pick a scheme. The first admin page after activation adds the demo catalogue once (your own products are never changed) and fills the home blocks. The stage is a normal Products block with the template "Product stage (Noir theme)": choose its products like any other block. Switch layouts in Design > Layouts. Licence: one production domain, 12 months of updates; staging and local copies are free. Without a valid licence the store shows the standard Responsive look and keeps selling.

Initial release: Noir, a dark-first luxury flagship theme (child of Responsive) for CS-Cart, CS-Cart Ultimate,

Tested on CS-Cart 4.17.2, Multi-Vendor 4.17.2. First release.
Does Noir work with my add-ons?
Yes. Noir is a child of the standard Responsive theme: no core files are changed and add-on hooks keep working (the theme carries its own copies of a few small storefront templates, as every Kavio theme does). Kavio Labs add-ons are styled to match each scheme.
Does it work on CS-Cart and on Multi-Vendor?
Yes, one package for every edition (CS-Cart, CS-Cart Ultimate, Multi-Vendor and Multi-Vendor Ultimate). On Multi-Vendor it adds the seller line on cards and styles the vendor pages.
Is Noir only dark?
No. It is dark by default (Basalt) and ships four more dark schemes plus three light ones (Porcelain, Pearl, Quartz). The homepage stage stays dark in the light schemes as well: it is the theme's spotlight.
Will my product photos look right on a dark page?
Yes. Product photos always sit on white plates (cards, stage disc, category discs, product gallery) and no colour filter or blend mode is applied, so products keep their real colours. Photos on a white or transparent background look best.
Can I switch the pointer spotlight off?
It only runs with a mouse or trackpad, never on touch screens and never for visitors who ask for reduced motion. The light passes under the photo plates, names and prices, so product colours are never tinted. To remove it entirely add .no-spot-on .no-lit:before { display: none; } in the Theme editor's custom CSS.
Why does a product show no countdown?
Countdowns only appear for catalog promotions with an end date. Noir never shows invented timers.
What happens without a licence?
A new installation works for 14 days. After that, without a valid licence, the storefront shows the standard Responsive look; cart, checkout and orders keep working and visitors see no message. The admin panel tells you why and how to fix it. See Configuration.
Does the theme work on my staging copy?
Yes. Subdomains of your licensed domain and local development hosts are covered by the same licence.
What happens if your licence server is down?
Nothing visible: the theme keeps the last verified result and keeps working for 14 days while it retries.
Will an update overwrite my changes?
No. Files you changed are kept (a notice lists them), and layouts and blocks are never replaced.
A campaign-driven theme: flash bar, bento hero with a live deal tile, flash-deals zone with countdowns, sticker discounts and promo cells inside your product grids.
