/**
 * SIB Institutional Events Calendar v3 — all views + filter bar.
 *
 * v3: SIB brand colors (Brand Guidelines pp. 17–20) are the DEFAULTS.
 * The full palette is declared as --sib-* custom properties, and every
 * component variable maps onto it. Any component variable can still be
 * overridden per instance from the WPBakery Design tab (scoped <style>
 * block) or globally in a child theme — the cascade is:
 *
 *   brand default  <  per-instance WPBakery picker  <  child-theme CSS
 *
 * Component variables:
 *   --sibec-accent            Links, active states       (Burgundy 500)
 *   --sibec-head-bg / -text   Weekday header row         (Navy 500 / Off-White 100)
 *   --sibec-today / -text     Current-day highlight      (Mustard 500 / Dark Gray 900)
 *   --sibec-filter-*          Filter + toolbar buttons   (Off-White / Dark Gray / Burgundy)
 *
 * Typography and radii still inherit The7 — only color defaults are branded.
