Heat Maps Component
A responsive heat map component for a portfolio, designed with a dark background and vibrant, high-saturation colors to reduce eye strain and create energy. Includes a calendar-like grid to visualize activity, interactive tooltips (though functionality is not implemented as per `no JavaScript` rule, visual placeholder is present), and a color legend.
