"ByteSized Tech" 是一张科技测评频道的 YouTube 横幅，采用利落的极简风格。白色加电光蓝的双色频道名和一行「诚实测评」短句放在深色桌面中央，左边是一部无品牌手机，右边是一副耳机。可以换成你自己的频道名和数码产品。

Create a finished YouTube channel banner, 2848 × 1600 px, 16:9. Render the exact channel name “ByteSized Tech” as the only headline and “Honest reviews, no hype” as the only supporting line; preserve spelling, capitalization, and punctuation exactly. Use crisp, custom geometric sans-serif lettering: heavy but not condensed headline, clean open counters, flat terminals, carefully spaced; render the name in matte warm-white with a restrained cool-cyan accent on “Tech.” Set the tagline smaller in a thin, highly legible warm-white sans-serif. Keep ALL text and key objects inside YouTube’s central safe band: x=20–80% and y=35.5–64.5% of the full canvas. Center the headline around x=50%, y=47%; place the tagline centered beneath it around y=58%. A slim modern smartphone lies face-up on a dark desk to the left of the headline, and a pair of wireless earbuds with their open charging case sits to the right; keep both props fully within the safe band, clearly visible, and subordinate to the name. The phone screen is dark with a few abstract, unreadable interface shapes only—no extra words, logos, or icons. Build an edge-to-edge charcoal-to-deep-navy gradient background with a subtly visible matte desk plane, controlled soft reflections beneath the devices, and a narrow cool-cyan rim light on device edges. Keep the area behind the type smooth and low contrast. Leave the outer canvas as crop-safe background only: no text, logos, handles, borders, frames, or key objects outside the central safe band. Flat, precise type; realistic product photography; crisp edges, restrained lighting, high contrast at small viewing sizes.
