v0.3.9

What's Changed

Changed

• Subtler device chassis bezels. Mobile ring dropped from 10 px to
  6 px, rounded from 2.5 rem to 2 rem, shadow from 2xl to xl. Tablet
  ring from 6 px to 5 px. Desktop ring color in light mode bumped from
  zinc-300 to zinc-200 so the 2K preset (and other desktop sizes) reads
  as a thin rectangular frame, not as "no frame at all" against the
  light chrome. Mobile chassis-decoration positions (speaker slot +
  home indicator) adjusted to match the new ring thickness.

• More breathing room between chassis and dimension badge. Badge
  margin-top from 0.5 rem to 1 rem so the W × H (Z %) readout no
  longer sticks against the chassis edge.

• Rotation: single icon-only button replaced by a 2-state segmented
  switch. Old button toggled previewRotated and showed a phone +
  curved-arrow glyph that meant "click to rotate" — actionable but
  with no visible state. The new switch is two adjacent buttons:
  a vertical-rectangle (Portrait) and a horizontal-rectangle
  (Landscape), with the active orientation highlighted. The user
  reads which orientation they're in at a glance instead of guessing
  what the toggle will produce. New setOrientation(rotated) store
  method backs the explicit-value semantics; the old toggleRotation()
  remains for keyboard shortcuts or programmatic callers that prefer
  the toggle shape.
