+# Pure CSS Pulse-Active Minimalist Tech Tooltip
+
+A declarative, highly efficient, zero-JavaScript tooltip system designed specifically for telemetry arrays, technical operation readouts, and minimalist monitoring dashboards.
+
+## Features
+- **Zero Scripting Threads:** Operates continuously using native CSS `@keyframes` properties paired safely with pseudo-interaction selectors.
+- **Dual-Layer Active Pulse:** Combines a fluid component-level scale transformation loop with an external radiating lightwave expansion trace.
+- **Cyber Minimalist Theme:** Styled around clean dark parameters, sharp structural borders, and standard monospace telemetry configurations.
+- **Fully Accessible UI:** Integrates semantic labeling parameters and distinct target rings for fast accessibility tracking.
+
+## Configuration Tokens
