   Palette: deep aubergine ink on pale lavender paper, with garnet / citrine /
   sapphire accents — a "typeface jewel-box" concept that matches the brand
   name and the product (each font style is presented like a cut gem).
   Type: Instrument Serif (display) + Manrope (body/UI) + IBM Plex Mono (labels)
   Signature: faceted "gem-cut" corner on cards, used sparingly.
