;;; fortune-gold-theme.el --- Warm fortune-inspired light theme -*- lexical-binding: t; -*-

;; Author: nobu43
;; Version: 0.1.0
;; Package-Requires: ((emacs "28.1") (modus-themes "5.0.0") (ef-themes "2.0.0"))
;; Keywords: faces, theme

;;; Commentary:
;;
;; A warm light theme built on the `modus-themes' engine and the `ef-themes'
;; palette semantics.
;;
;; The palette follows a fortune-oriented direction: yellow/gold is the primary
;; accent, warm white and beige form the base, while water blue, lavender, pink,
;; red, orange, silver, and restrained green support syntax and status faces.
;; Syntax colors are intentionally kept close to WCAG AA contrast against the
;; main background so they remain vivid while readable.
