/*
 * treatment.css -- shared styling deltas for the eight zone editor pages.
 *
 * Most of the visual surface for the treatment editors reuses the legacy
 * `.ml-*` classes already shipped in panel.css (toolbar, tile grid, bucket
 * tile mosaic, detail drawer, bulk bar) and the NEW ADMIN `.ui-*` classes
 * already shipped in ui-components.css / ui-shell.css (cards, forms, table,
 * pills, buttons, notices). This file adds only the deltas the framework
 * needs that those two systems do not already cover, namely:
 *
 *   - .tx-card          : a treatment-page card wrapper
 *   - .tx-subtabs       : horizontal sub-tab strip per treatment detail
 *   - .tx-section-status: the read-only "section is enabled on site" pill row
 *   - .tx-about         : the per-page / per-sub-tab help panel
 *   - .tx-schedule-row  : compact row used for milestone / release / rotation entries
 *   - .tx-empty         : tiny empty-state used by zone-specific cards
 *
 * Stays in the ui-* token system: never invents colors; reads
 * --c-text / --c-bg / --c-border / --c-primary / --c-text-muted /
 * --c-surface from tokens.css, and reuses the existing radii / spacing.
