/* Keyword Gap Analysis - tool-specific overrides on top of the shared
 * primitives in code/assets/css/tools.css.
 *
 * What lives here:
 *   1. Page-chrome (tightening header padding for this tool's hero).
 *   2. Form-field labels we add above the user input and competitor
 *      textarea.
 *   3. Wide results table: 2-row header treatment (competitor name
 *      spans Traffic + Position subheaders), per-column widths, and
 *      the centered+bold numeric cell styling shared with TPF.
 *   4. Results subhead chip (resolution + per-input keyword counts).
 *   5. Modal-backdrop reuse + invalid/unknown list styling. Same shape
 *      WTC and TPF use; the `.modal-backdrop[hidden]` override is
 *      mandatory because display:flex would otherwise beat [hidden].
