    === RULES ===

    1) SURFACES must be TINTED with the theme color — never gray or neutral.
       bg is lightest (pastel), then input, section, secondary, nav (deeper), btn (deepest or vivid).
    2) ALL text must be DARK (#0a-#2f range) on light themes, LIGHT (#cc-#ff range) on dark themes.
       Exception: text-on-btn must contrast with surface-btn. If btn is dark, text-on-btn is light.
    3) brand/link = vivid theme color. danger=red, success=green, warning=amber ALWAYS.
    4) code-bg = same hue as surface-bg, slightly darker. NEVER a different hue family.
    5) Multi-color prompts (e.g. "Google logo", "rainbow", "Italian flag"):
       - Surfaces: use the DOMINANT color's hue (tinted, not gray)
       - Distribute each distinct color to: brand, active, badge-bg, accent-border, accent-text
       - Each color must be RECOGNIZABLE — never blend into one muddy tone
    6) Match the vibe: "토마토" = warm reds/oranges, "바나나" = bright yellows, "ėˆē" = rich greens.
       The user should IMMEDIATELY recognize the theme from its colors.
    7) CREATIVE TREE STYLING — the app has a hierarchical list (outliner) with levels:
       - Level 1-3: headings (h1/h2/h3). Level 4+: bullet items.
       - Items at level 1-3 WITHOUT children render as plain text (childless style).
       - creative-h{1,2,3}-size: font size (em units). h1 largest, descending. Range: 1.0em-1.5em.
       - creative-h{1,2,3}-weight: font weight. h1 boldest. Values: 400-800.
       - creative-h{1,2,3}-color: heading colors. Use text-primary or theme accent for h1.
         h3 can use muted color. MUST be readable on surface-bg.
       - creative-childless-size: usually 1em (normal text size).
       - creative-childless-weight: usually 400 (normal weight).
       - creative-bullet-size: bullet dot diameter in px. Range: 3px-6px.
       - creative-bullet-color: bullet color. Can match brand or text-primary.
       - creative-tree-line-color: vertical guide line color. Usually border-color or muted.
       - creative-tree-line-opacity: 0.3-0.8. Subtle but visible.
       - creative-h{1,2,3}-bg: heading row background color. Usually "transparent".
         For dark/accent themes, h1 can use a subtle darker surface. Must not clash with text.
       - For playful themes, vary heading colors. For minimal themes, keep sizes uniform.

    { role: :system, parts: [ { text: system_prompt } ] },
