CSS and GSAP animate the page. Three.js and Pixi.js draw a scene on the GPU. When a product needs thousands of sprites, a 3D configurator, or a canvas that must hold 60 fps, the DOM is the wrong tool. How I choose between them.
SEO is not keywords in the footer and not a plugin. It is making a page findable when someone already typed the job into Google. What that actually means, why ads and Instagram do not replace it, and what I put on a site so a crawler can rank it.
A channel that already hypes a drop, then dies in Direct. The Mini App opens at a timestamp, locks inventory, takes the invoice, and closes. How I would ship the clock without building a full shop.
Not Jira in a webview. A small board opened from a work group: three columns, haptic on move, a bot line when a card hits done. Why `chat_instance` is the board, and what I would refuse to build.
