// MLSYSBOOK SHARED BASE STYLES - CANONICAL REFERENCE
|
|
// =============================================================================
|
|
// This is the SINGLE SOURCE OF TRUTH for shared styles across the ecosystem.
|
|
//
|
|
// Due to Quarto's SCSS format limitations (can't use @import between
|
|
// /*-- scss:defaults --*/ and /*-- scss:rules --*/), this file cannot be
|
|
// directly imported. Instead, it serves as the REFERENCE TEMPLATE.
|
|
//
|
|
// ARCHITECTURE:
|
|
// - book/quarto/assets/styles/style.scss -> Uses $crimson (#A51C30)
|
|
// - kits/assets/styles/style.scss -> Uses $kits-accent (#148F77)
|
|
// - labs/assets/styles/style.scss -> Uses $labs-accent (#7D3C98)
|
|
//
|
|
// Each project file should MIRROR the patterns in this file, only changing
|
|
// the accent color variable. When updating shared styles:
|
|
// 1. Update this file first
|
|
// 2. Copy the changes to book, kits, and labs stylesheets
|
|
// =============================================================================
