A pure QML component that calculates velocity from a series of position events (x, y, timestamp). It uses a sliding window of recent points to compute instantaneous velocity, which is essential for swipe gesture detection and kinetic scrolling. The component is self-contained, depends only on QtQuick, and can be reused in any QML project requiring velocity-based gesture handling.

A QML component that displays scrolling text when the content exceeds the available width. It animates the text horizontally in a loop, with configurable speed and pause duration. This is a common mobile UI pattern for displaying truncated labels (e.g., song titles, notification summaries). The component is self-contained and depends only on QtQuick, making it easily reusable.

A QML component that renders a drop shadow behind text using a layered approach with opacity and offset. It provides a configurable shadow color, radius, and offset, and is designed to be lightweight and performant. This is useful for improving text readability over dynamic backgrounds (e.g., wallpaper). The component is self-contained and depends only on QtQuick.

A QML component that applies an opacity gradient to the top and bottom edges of a Flickable to indicate scrollable content. It uses a ShaderEffect or layered rectangles to fade the content at the boundaries, providing a visual cue that more content is available. This is a common mobile UI pattern. The component is self-contained and depends only on QtQuick.

A QML component that displays a relative timestamp (e.g., '2 minutes ago') that automatically updates every minute. It takes a Unix timestamp as input and formats it using a configurable locale. This is a reusable pattern for any notification or feed UI that needs to show relative time. The component is self-contained and depends only on QtQuick.
