/* =====================================================================
   PlannrPro Design System — "Quiet Clarity"
   One shared stylesheet for every PlannrPro surface (booking, manage,
   paid, admin). Tokens first, then base elements, then components.

   Identity (in the spirit of Resend, deliberately NOT Biflus): pure white
   content, near-black ink, ONE clean system sans with a strong hierarchy,
   HAIRLINES instead of cards, and colour used only where it means
   something. The signature is a single warm AMBER (#b9791b) reserved for
   what is LIVE or SELECTED — a chosen time, a live hold ticking down, the
   active nav item, "today", key figures. PRIMARY actions are near-black.

   All existing class names are preserved so behavior/JS hooks are
   untouched; this file is pure presentation. Light-only for now (status
   pills carry inline tint backgrounds that assume a white field).

   Per-business branding: booking/manage JS overrides --brand (+ its soft
   / line / ring derivatives) with the company's colour, so their hue
   becomes the *accent* (slot hover, focus, live hold). Primary buttons
   stay near-black regardless, keeping every business premium & consistent.
