/* =============================================================================
 * Organic Calendar (widgets/OrganicCalendarWidget.php, web/js/organic-calendar.js)
 *
 * Calendar left, persistent agenda right (55 / 45, stacked on phones).
 * Every populated date wears ONE soft organic circle in the brand's primary
 * green; its diameter is  cell width x (0.44 + 0.44 x --oc-ratio), where
 * --oc-ratio is the bounded square-root density (1 event = 0, 10+ = 1). The
 * cells are square and the circle never exceeds 88% of the cell, so circles
 * can never touch a neighbouring date. Shade deepens slightly with density,
 * but size alone carries the meaning. Selection is a separate outline ring,
 * today a small dot - neither changes the density encoding.
