   Theme ids are the ones buyers already have saved: blush, neutral, dark,
   plus rainbow (offered by onboarding since V1). Never rename them.
   Page stays light and neutral; colour lives in the menu, buttons, chips,
   charts and progress bars. Text on every pastel is a deep shade of the
   same hue (contrast checked: body 7:1, small text 4.5:1, icons 3:1). */
