/*
 * Shiko WhatsApp Bot — OTP/auth form styles
 * 2.18.0 — folded from custom-auth-plugin per "no parallel plugin" rule
 *
 * Scoped to .shiko-otp-* selectors only — NO global styles (defers cap CR #5).
 * Logical properties only for RTL safety (margin-inline-*, inset-inline-*).
 * Brand tokens: --shiko-primary (#B7080A), --shiko-accent (#E40303).
