Review comment (refactor):
The session management UI is embedded directly in DropdownGroup.svelte, which violates the single responsibility principle.

Looking at the codebase structure, there's already a dedicated `SessionManager.svelte` 

DropdownGroup.svelte now handles patterns, models, languages, strategies, sessions, AND pattern variables

Other components, like `Models.svelte` and `Patterns.svelte`, are dedicated to single concerns.

The component is becoming a "god component".

Recommendation: Extract the session input/selection UI into a separate `SessionSelector.svelte` component following the pattern of existing components:

Code after:
<script lang="ts">
  import Patterns from "./Patterns.svelte";
  import Models from "./Models.svelte";
  import ModelConfig from "./ModelConfig.svelte";
  import SessionSelector from "./SessionSelector.svelte";
  import { Select } from "$lib/components/ui/select";
  import { Label } from "$lib/components/ui/label";
  import { languageStore } from '$lib/store/language-store';
  import { strategies, selectedStrategy, fetchStrategies } from '$lib/store/strategy-store';
  import { patternVariables } from '$lib/store/pattern-store';
  import { onMount } from 'svelte';

  const languages = [
    { code: '', name: 'Default Language' },
    { code: 'en', name: 'English' },
    { code: 'fr', name: 'French' },
    { code: 'es', name: 'Spanish' },
    { code: 'de', name: 'German' },
    { code: 'zh', name: 'Chinese' },
    { code: 'ja', name: 'Japanese' },
    { code: 'it', name: 'Italian' }
  ];

  let variablesJsonString = '';

  // Parse JSON string and update variables store
  function updateVariables() {
    try {
      if (variablesJsonString.trim() === '') {
        patternVariables.set({});
      } else {
        const parsed = JSON.parse(variablesJsonString);
        if (typeof parsed === 'object' && parsed !== null && !Array.isArray(parsed)) {
          patternVariables.set(parsed);
        }
      }
    } catch (e) {
