 * Donovan Legal PLLC — RESERVE Structuring Tool (Advisory)
 * Tool-specific stylesheet
 * ----------------------------------------------------------------------------
 * Load order: main.css -> tool-form-shared.css -> tool-structuring.css
 *
 * Conventions:
 *   - .struct-* classes for tool inputs (parallels .oa-* in Tool #1)
 *   - .memo-* classes for the memorandum preview pane (print-grade)
 *   - Brand: RESERVE two-tone is applied at the HTML level via
 *     <span class="brand-reserve"><span class="re">RE</span>SERVE</span>
 *   - Colors mirror main.css for cross-site consistency:
 *       #169B62 firm emerald     (RE in two-tone, links, primary accents)
 *       #0A4A2A deep firm green  (header bar)
 *       #5fc88e light emerald    (RE in dark headers, for contrast)
 *       #c5c6c8 platinum silver
 *       #C9A961 gold
 *       #F5F5F0 paper / page bg
 *       #d4d4d0 divider lines
 *       #1a1a1a body copy
