/*
 * TeachLuma Games — shared brand theme.
 * Loaded by every game AFTER its own inline <style>, so these rules win on
 * equal specificity. Games are built on the same variable names
 * (--brand-*, --ink*, --border, --subject-math*); remapping them here
 * re-themes every game in one place, and the component rules below add
 * the brand's fonts, gold CTAs, rounded answer tiles and cream backdrop.
 * If this file fails to load, each game still renders with its own colors.
