/*
 * Evidence Custodian - Contextual Help ("?") Tooltips
 * =====================================================
 * A small "?" affordance next to a field label. Hover or focus previews
 * it; click/tap/Enter/Space pins it open (help-tip.js) so it also works
 * on touch devices, where there is no hover. Colors reuse the navy/gold
 * variables already defined by each page's own <style> block - this
 * file only adds the component, not a new palette.
