LCARS UI Foundations

LCARS (Library Computer Access/Retrieval System) is the iconic, flat, colorful operating system interface from the Star Trek universe (specifically the TNG era). This skill provides the core design tokens and layout strategies needed to replicate it strictly with HTML and CSS.

The LCARS Philosophy

LCARS is characterized by its stark contrast, distinct blocky shapes, tight grouping of related elements, and functional aesthetic. There is no shading, no gradient (usually), no borders, and no drop shadows.

Design Tokens (CSS Variables)

Define these core variables at the root of your CSS to ensure consistency:

:root {
  /* The mandatory background */
  --lcars-bg: #000000;
