/* Plink landing — shared stylesheet
 *
 * Brand palette mirrors src/constants/colors.ts (lavender 10-step) so the
 * landing visually flows into the app the moment a user taps "Try the
 * web app". Pure system font stack matches the app's own choice — no
 * web font request = no flash, no privacy hop, no cookie banner.
 *
 * Layout reference: Linear (typography hierarchy + measured spacing),
 * Notion Calendar (real product preview as the hero's centerpiece),
 * Toss / Linear Korea (clean lavender + dark text). Mobile-first. The
 * only JS is i18n.js — the page is fully readable with JS off because
 * default text in HTML is English.
