Create a high-quality horizontal web banner for a course promotion, intended to function like a 1200×300 banner. The banner is for a Japanese audience and should target women who are interested in learning practical website maintenance. Make it clean, trustworthy, professional, and visually appealing with a business atmosphere, while still feeling approachable and elegant.
Design goal: attract attention quickly. Prioritize strong visual hierarchy, high contrast, generous negative space, and immediate readability even on small screens.
Layout: left side for text, right side for the main visual. Keep the composition balanced and uncluttered.
Main visual on the right: a friendly, professional Japanese woman in her 30s to 40s, neat and approachable, working on a laptop in a bright modern workspace. Include subtle website-management related visual cues such as a website dashboard on screen, shield/security icon, backup/cloud icon, and maintenance/settings motifs in a polished, integrated way. Do not use any brand logos.
Text must be in Japanese and clearly legible. Render the following text exactly and elegantly:
Main headline: "WordPress保守・管理講座"
Subheadline: "更新・バックアップ・セキュリティをやさしく学べる"
Support text: "初心者でも安心の実践講座"
CTA button text: "講座を見る"
Typography: bold, clean Japanese sans-serif, with the main headline large and prominent. The subheadline should support the main message without clutter. CTA should look clickable.
Color palette: white and light background with navy, soft blue, and a subtle lavender accent to suit a business-oriented but female-friendly design. Premium and polished, not overly cute.
Style: modern online course advertisement, commercial-quality banner, clean grid, crisp edges, refined spacing, practical and conversion-oriented design.

Decorative style:
Add playful educational motifs like pencils, stars, dots, pastel shapes, bunting flags, and small doodle accents around the banner.
