/* ============================================================================= MINIMAL_TEXT — a minimal, typographic design language. "typography is the design. if it doesn't need to be there, remove it." One drop-in stylesheet: the typeface, the tokens (light + dark + system), a base reset, and the full component layer as framework-agnostic classes. Two colors + one muted accent. Inter 300/400 only. Square (one 3px radius). No shadows, no gradients, no rgba overlays, no blur. Whitespace is structural. Distilled from the "sasidharan gs" system. Portable & renamable: every class is prefixed `mt-`; every value is a custom property. Theme via (omit to follow the OS). ============================================================================= */ /* ---- Typeface -------------------------------------------------------------- */ @font-face { font-family: "Inter"; font-style: normal; font-weight: 100 900; /* variable axis; we only ever use 300 & 400 */ font-display: swap; src: url("./assets/fonts/Inter-Variable.ttf") format("truetype-variations"); } /* ---- Tokens: light (default) ---------------------------------------------- */ :root, :root[data-theme="light"] { /* Palette — two colors + a muted tint.
