/* Loop Lab.

   The look (Kalle's brief, 11 October 2026): a clean, restrained practice tool. A light neutral
   page, white surfaces, purple as the one colour of action. Whitespace and thin separators
   divide things, not boxes inside boxes. The player is the centre: waveform, play, speed and
   pitch. Everything else is a quiet row under it that opens when asked.

   One size of control (40 px, 44 on touch), one corner radius (10 px; 14 for surfaces), one
   font. Labels are small and grey, values are dark, and only the play button is loud.

   Layouts: 900 px and wider is the full layout; narrower stacks speed over pitch and the
   transport; under 560 px is the phone layout, with a play bar that sticks to the bottom. */
