/**
 * Arbor (K5) — Sponsor Dashboard Styles
 *
 * Colour and type come from ../shared/brand.css (Brandbook §3/§4). No hex
 * literals live in this file — the previous palette (#1F6F6B / #155551 /
 * #E2F0EF / #152226 / #5C6B72 / #c8d3d8 / #B23A2E) was the archived
 * CohortTrials teal and shared no colour with the Arbor brandbook.
 *
 * Contrast corrections made here:
 *   - disclaimer banner was #9A6B00 on #FBF0D6 (4.14:1) -> --flint-text on
 *     --flint-surface (6.05:1)
 *   - .topbar-subtitle / .topbar-user were white at 75%/90% opacity on the
 *     header (4.11:1) -> full-opacity --mist
 *   - .chip-green/.chip-active were #1E7F4F on #E3F3EA (4.35:1) -> --ok on --ok-bg
 *   - input borders were #c8d3d8 on white (1.53:1, below the 3:1 required of a
 *     non-text UI boundary) -> --border-input
 *   - `.field input:focus { outline: none }` plus a 12%-opacity box-shadow is
 *     not a perceivable focus indicator; removed so brand.css :focus-visible
 *     applies.
