 * ph-core.css — NEUTRAL base styles for the shared window.PH components.
 * -----------------------------------------------------------------------------
 * These styles are intentionally MINIMAL and structural. They read CSS custom
 * properties so each variant themes the shared widgets by defining:
 *   --ph-accent   primary accent / brand color
 *   --ph-bg       app background
 *   --ph-surface  panel / card background
 *   --ph-text     primary text color
 *   --ph-border   border color
 *   --ph-radius   corner radius
 * Optional extras (with safe fallbacks below):
 *   --ph-muted    secondary text
 *   --ph-danger / --ph-warn / --ph-ok  status colors
 *   --ph-shadow   elevation shadow
 *   --ph-overlay  modal backdrop color
 *
 * Variants OWN their look — only override these here if a variant does not.
 * ========================================================================== */
