0.1.11 left it at 40px with line-height 1.45, so the line (20.3px) overflowed
the 20px content box — taller than the <input> it replaced, and liable to show a
scrollbar on a single line.
Collapsed height is now one token, --miu-composer-h: 38px, shared by the
textarea, attach and send so they cannot drift apart again. Padding tightened to
8px (from .miu-input's 9px) with line-height 1.4, so a 14px line is 19.6 + 16 + 2
= 37.6px and fits exactly — matching the original single-line input.
