/* Fluent 2 page styles — people module. Uses only tokens from fluent-tokens.css (no hex, no raw px for
   spacing/type). Loaded after styles.css. Owned by the people pages; keep selectors scoped to them.
   Pages: #students #teachers #parents-manage #teacher-rates #users-manage #my-students #teaching-profile
   #my-account, plus the people dialogs (add/edit student, teacher, parent, admin, reset password, profile).
   Shared building blocks use the `ppl-` prefix:
     .ppl-card            white card (one level only — never inside another card)
     .ppl-card-head       card header row: icon + title (16px) + subtitle (12px) + optional end actions
     .ppl-row             Microsoft "settings card" list row: icon | title + description | value / action
     .ppl-profile         profile header on the canvas: avatar circle + name + username chip + role
     .ppl-fields          a row of content-sized form fields (.ppl-w-xs/-s/-m/-l/-name on the .form-group)
     .ppl-form-actions    form / dialog actions (dialogs: end-aligned, primary last)
     .ppl-dialog          marks a people dialog body (sizes the Fluent dialog to 600px / 480px) */
