+ * Style presets:
+ *   - 'blur'  (default) — blurred+dimmed copy as background, image centered with shadow
+ *   - 'dark'  — dark background (#2a2a2a) with shadow
+ *   - 'light' — white background with shadow
+ *   - 'full'  — image covers entire screen, no padding/shadow
+ *
+ * Custom background overrides the preset (e.g. background: '#003366').
+ *
+ * @param {string} imagePath — path to the image file (PNG, JPG, etc.)
+ * @param {object} [opts]
+ * @param {'blur'|'dark'|'light'|'full'} [opts.style='blur'] — display style preset
+ * @param {string} [opts.background] — custom background color/gradient (overrides style preset)
+ * @param {boolean} [opts.shadow] — show drop shadow (default: true for blur/dark/light, false for full)
+ * @param {string|false} [opts.speech] — TTS narration text while image is shown.
+ *   Pass a string for narration, or false to skip. Omit to skip (no auto-text for images).
