/*
  Mukhtar Partner Console.

  This runs on whatever device the restaurant has at the counter, which in
  practice means an old Android phone with a cracked screen under bright
  lights, held by someone with a queue in front of them. Every choice here
  follows from that:

  - Light, very high contrast. Dark themes look good in an office and wash
    out under restaurant lighting on a cheap panel.
  - Nothing smaller than 16px, and touch targets at 56px and up.
  - No animation that delays an action. The only motion is feedback.
  - One column, always. No layout that depends on width.

/* ── Cold start ────────────────────────────────────────────────────────
   Two beats, identical in all three Mukhtar apps.

   One: brand green fills the screen and the white falcon wipes in top to
   bottom, the eye pops, MUKHTAR rises.
   Two: the whole thing inverts. Green ground snaps to white, mark and
   wordmark snap to green, held a moment, then the till screen appears.

   The flip is a hard cut, not a fade. Fading it would read as the splash
   petering out; snapping reads as a deliberate signature. `steps(1, end)`
   is what makes it a cut rather than a blend of two greens. */
