[Purpose]
Create ONE finished dark minimalist phone wallpaper with one original black cosmic planet and one large pencil-handwritten personal sentence. A phone owner sets it directly as their lock-screen image, keeping a small line they want to see each day. This card always produces the same quiet black-space composition. It is not a realistic astronomical observation, an astrology reading, a quote poster, an image collection or a phone mockup. Draw the complete wallpaper now on one canvas.

[One fixed cosmic scene]
Use a near-black space background, with only a handful of tiny faint gray distant points. Most of the upper canvas stays completely calm and empty. One large charcoal rocky planet fills the lower-right area, seen as a dark sphere with a thin warm ivory highlight and a restrained terracotta-red rim along its upper-right edge. The sphere's center lies around x=70%, y=75%; its diameter is about61% of canvas width. Keep the sphere readable; let its right edge meet the canvas edge, while its lowest contour stays above the bottom. Its dim body has subtle irregular mineral texture and believable spherical shading. There is only ONE planet, without rings, a second moon, a galaxy collage, spacecraft, cars, people, animals, mountains or an additional fantasy object.

[Resolve the owner's words]
Personal sentence input: "【残す一言】". Sentence tone input: "【言葉の調子】". If the sentence is "おまかせ", use exactly "自分だけの軌道で" when the tone is "しっかり", and exactly "自分の速さで輝く" for automatic or gentle tone. For any custom sentence, render the supplied words exactly regardless of tone. Never print the automatic control or tone label. This is an original personal line, without a famous author, attribution, diagnosis, prediction, success guarantee or claim that the planet is a real discovered object. Do not add a title, explanation, date, clock, notification, device model or second affirmation.
Optional personal name: render "【自分の名前】" once as a small legible cream pencil signature at 55–58% in the left12–32% of canvas width, only when supplied.

[Fixed lettering and placement]
Keep the top30% fully clear for the phone owner's real clock and interface. Do NOT draw a clock or simulated app interface. Place the one main sentence between 32–53% of height, centered slightly left of the sphere, using at most two natural lines. Draw LARGE warm-cream colored-pencil handwriting with broad readable strokes, delicate pencil grain and simple natural Korean, English or Japanese letterforms as appropriate. All letters must be easy to read at the small list-thumbnail size; this is expressive handwriting, not tiny elegant calligraphy. Avoid cursive connections that hide word boundaries, decorative Latin filler, emoji and quotation marks. The optional name has its own smaller line below the sentence in the dark left margin, clearly beside rather than over the planet. Leave bottom15% free of important words. Keep the pencil words distinct from stars and never overlap the planet's bright rim. The user should not need to crop or add any lettering.

[Style and visual hierarchy]
The main field is deep charcoal-black, with sparse matte cosmic illustration rather than a glossy science-fiction movie poster. The planet has one warm edge and restrained rock grain; its shadow merges gradually with the black space while its sphere remains visible. The handwritten sentence is the brightest broad shape, followed by the planet's small illuminated edge. Black negative space must remain at least60% of the canvas. Keep the background quiet with no neon halo, lens flare, floating dust storm, explosive nebula, spark shower, rays or heavy texture behind the words. There is no rectangular text panel, answer ribbon, border, paper collage, silhouette figure or duplicated planet. The letter color and composition stay fixed; the fields change only personal wording and an optional name.

[Aspect ratio and completion]
The site supplies the portrait ratio above, either9:16 for the phone image or2:3 for a matching complete card image. Preserve the same relationships between the top blank area, large pencil sentence and one planet in both ratios; recompose gently within the canvas instead of cutting an existing image. Do not offer a second wallpaper or ask for a screen model. Render visible personal text in Japanese, retaining supplied spelling exactly. The result must be usable as the one saved image itself, with no extra assembly, code execution or follow-up step.

[Text rules and delivery]
Resolve automatic copy controls before drawing; their literal input is not artwork. Render only the specified visible words, with natural spelling and strong contrast. Never print field labels, instruction headings, quotation marks, language labels or your reasoning. Match every supplied name and number character by character. Do not fabricate a date, discount, award, availability, biography, health benefit, personality diagnosis, quotation attribution or advertising condition. Keep decorative marks separate from legible letters. The fixed style and composition are part of this card; user inputs change its personal content only. Deliver exactly ONE complete raster image in this response. Do not run code, offer alternatives, produce separate pages, ask the user to type next, or require cutting and assembling the result. No device mockup, browser interface, watermark, publisher logo or branded character. Use the requested output aspect ratio and finish all content within that one canvas.
