-                <li>Completed a deep audit to optimize <strong>launch time</strong>, <strong>memory usage</strong>, and overall <strong>efficiency</strong>.</li>
+                <li><strong>Semantic Search.</strong> Zaguán Blade now analyzes your codebase and builds a deep reference map that the model can query semantically.</li>
+                <li><strong>Smarter Context Retrieval.</strong> Instead of pulling broad chunks of code, the model can now pinpoint the most relevant symbols, files, and references it actually needs.</li>
+                <li><strong>Lower Token Usage.</strong> Semantic search helps reduce context size while improving response quality and precision across code understanding tasks.</li>
                 <li>Fully implemented <strong>i18n</strong> for <strong>Zaguán Blade</strong>, with <strong>English</strong> and <strong>Spanish</strong> now available.</li>
                 <li>Updated to <strong>Vite 8</strong>.</li>
                 <li>Updated <strong>CodeMirror</strong> modules to their latest versions.</li>
                 <li>Updated many outdated <strong>Rust crates</strong>.</li>
                 <li>Replaced a select few commands with built-in commands for better cross-OS compatibility.</li>
                 <li><strong>Zaguán Blade.</strong> Disabled a lot more debug output throughout the app.</li>
