/* Module: lighting-tools
 * Scope: module-specific selectors use [data-module="lighting-tools"].
 * Colors: CSS custom properties only (both themes inherit from platform tokens).
 * Layout: full-bleed module that supplies its own gutter + centered wrap, then
 *         leans on platform components (strata-view-header, strata-card-grid,
 *         strata-mgmt-card, badge, input-field, btn-*) so it reads as native
 *         Strata. A landing card grid is the front door; each tool opens in a
 *         detail view. Tool-body widgets (DIP paddles, beam viz, tunable meter)
 *         stay module-specific but sit on platform surfaces.
