v1.0.3

• CIE: the spectral-locus horseshoe is drawn as a smooth spline through the
  5 nm table instead of showing straight chords on its fast-sweeping
  cyan-green edge.
• 4-scope layout: when one column holds only the square scopes (vectorscope,
  CIE) and the other only the stretchy ones (waveform, histogram), the
  vertical split now shifts automatically so the square column is exactly as
  wide as its graphs can use — the waveform/histogram column gets all the
  reclaimed width instead of leaving dead space beside the square scopes.
• Fixed: in the 2- and 4-scope layouts, the scope-type dropdowns no longer
  overlap the waveform's nit labels — they now start right of the label column.
• Scope-type dropdowns size themselves to the selected scope's name, so a
  short name like "Waveform" no longer blocks the graph with unused width.
• The floating controls (scope pickers and the top-right button strip) fade
  out while the mouse is outside the HDRScopes window, keeping the scopes
  unobstructed when you're just watching. A new Controls > Preferences >
  "Idle controls opacity" slider sets how visible they stay (default 5%,
  100% = never fade).
• GitHub Releases now include a summarized changelog (this file) instead of
  only the commit-diff link.
