/* style.css — LADS Resource Calculator
 *
 * Visual system extracted from mivvii.com (the live MIVVII store):
 *   - Font: Inter (clean sans-serif, used site-wide)
 *   - Palette: minimal black-on-white, generous whitespace
 *   - Buttons: 14px radius, solid near-black
 *   - Inputs: 4px radius; cards: ~12px radius, hairline border
 *   - Accent: in-stock green / warn orange for status cues
 * Mobile-first: base styles target phones; a min-width query refines larger screens.
 *
 * NOTE: This is MIVVII's OWN brand visual — no LADS official assets/colors used.
