/*
 * Bead Factory PH — styles.css
 * Design Concept: "Petal & Gold" — Artisanal Bead Jewelry, Philippines
 *
 * Palette derived from the brand logo: a close-up of a dusty-pink lily petal
 * with elegant white serif lettering. The pink petals (#C4887A warm rose-terra),
 * the olive-gold petal center (#B89868 antique gold), and the deep plum-noir
 * dark (#1A0E14) create a palette that is warm, feminine, and tactile — befitting
 * a handcrafted bead accessories brand.
 *
 * Fonts: Elsie (display, ornamental swash serif — artisanal / handcrafted energy)
 * + Jost (body, clean geometric humanist — readable & contemporary).
 * Both loaded via <link> in HTML. Never @import here.
