/* ==========================================================================
   Sign-in panel: controls sized for thumbs.
   
   Measured on a 390px viewport before changing anything:
     primary button        356x36   (below the 44px minimum)
     สร้างบัญชีใหม่          62x14   — a 14px tap target
     ลืมรหัสผ่าน             50x14   — 14px, and grey, so it read as plain text
     Google                372x39   — no border, no background: looked like text
     ดูแพ็กและราคา           372x39   — same problem, and barely visible

   Everything below is driven by those numbers: 44px minimum height on every
   interactive element, real affordance on the Google button, and one consistent
   link treatment instead of three different greys.
