/**
 * Before After - Common base CSS ( loads for every style ).
 *
 * Owns the shared skeleton: the frame, the clipped "before" layer, divider,
 * handle and labels for both orientations. The after image sits in normal
 * flow so the frame always sizes itself correctly ( no width / alignment
 * surprises ); a fixed aspect ratio switches it to absolute + cover.
 * Per-style files paint the divider, handle and label chrome.
 * CSS variables drive theme and sizing:
 *   --captwiki-ba-pos           → live divider position ( % )
 *   --captwiki-ba-line          → divider line colour
 *   --captwiki-ba-handle        → handle diameter
 *   --captwiki-ba-handle-bg     → handle background
 *   --captwiki-ba-handle-color  → handle arrow colour
 *   --captwiki-ba-ratio         → fixed aspect ratio ( when set )
 *
