/* Backlink Counter - tool-specific styles on top of the shared tool
 * primitives in code/assets/css/tools.css.
 *
 * Cross-tool primitives (mode toggle, input form, primary/ghost button,
 * progress region, errors region, results region, table base, sortable
 * headers, pagination, toasts, history region, sticky chrome, debug
 * panel, upgrade banner, modal chrome, quota banner, cell-xlink) live in
 * tools.css. Only the bits genuinely specific to this tool sit here:
 *
 *   1. Form layout (single input + submit; no country / type select).
 *   2. Single-mode big-number cards (Total Backlinks + Referring Domains
 *      lead; DA + Spam are smaller secondary cards).
 *   3. Per-column widths on the 7-column results table (counts-first).
 *   4. DA badge tiers (0-30 muted / 31-60 medium / 61+ strong) and
 *      Spam-score badge tiers (0-30 good / 31-60 warn / 61+ bad), shown
 *      as secondary metrics.
 *
 * There is NO DA-trend sparkline / zoom-modal CSS here: this tool leads
 * with backlink counts and does not surface the DA trend chart.
