We need answer only rewritten CSS. Need preserve selectors/layout. Change colors/shadows/radius/transitions/gradients etc. Conservative but previous didn't change enough. Need fresh palette target centered-stage: dark stage #0f0f1a, premium gold or deep purple accent, soft shadows multi-layer, large radius 12-24px, smooth transitions.

We need output CSS. Need ensure no comments? Original has comments. We can keep comments? Output only CSS, no AI marker comments. Comments original okay? Yes likely. But maybe no markdown fences. Need rewrite. Must preserve all selectors character-for-character. We can change CSS custom properties? They are not defined here except var usages. But task says custom properties values maybe if defined. There are no :root definitions in provided file. We can change color hex/rgba throughout. We cannot change layout. Need replace colors, shadows, radius, transitions. Some hardcoded colors: #fff, #475569, rgba etc. Change to palette.

Need be careful: border-bottom 2px solid var(--color-border) — border-width not change, color variable. We can keep var names but maybe redefine? Since no :root, changing var names not possible? We can keep custom property references; but visual identity depends theme vars maybe elsewhere. But in this file we can change literal colors and shadows. For vars, maybe not modify. But instruction says custom property values if present. None. Could add? No, selector additions? Probably shouldn't add :root? It might be okay? But HTML fixed, adding :root maybe fine, but not requested. Better not add new selectors. We can use fallback? No.

However to make more distinct, replace all hardcoded colors with fresh palette and modify shadows/radii. But many var(--color-*) remain, so if theme.css has blue, visual won't change much. Could override by using different vars? But var names fixed in HTML? CSS vars can be changed, but if not defined here, they inherit. We can add :root definitions? That changes visual identity. But "All color values" includes custom properties. Adding :root with updated values might be allowed? However selectors must preserve all selectors, but adding :root doesn't break. But task says output rewritten CSS preserving selectors; adding new selector maybe not ideal. Could also replace var(--color-primary) with literal gold? But then many places. If we replace var references with literal colors, we change selectors? No, values only. That could be more distinct. But careful: CSS custom property usage maybe intended. Since no :root in file, replacing with literals is allowed? "CSS custom properties values" not selectors. We can replace var(--color-primary) with #c9a227 etc. But might conflict with theme. However mission: visual identity refresh. Could replace all var color references with new palette literals. But some vars like --space-xs used for padding, that's layout. Must keep. So only replace color vars? We can replace var(--color-primary) with gold, var(--color-text) with dark etc. But if we replace --color-bg-soft with dark? Need be careful with text contrast. Target dark stage with bright content. But this CSS is for article/app pages. If we make backgrounds dark and text? We must not change layout, but colors can. Need ensure readability. Could use deep purple/gold accents with light backgrounds? Target says dark stage #0f0f1a, bright content area. But if we set section backgrounds to dark, existing text maybe white? Some sections use color #fff for hero. We can design: body? Not in file. We can set .app-qr-section background to var(--color-bg-soft) (likely light). Changing to dark could make text unreadable if text color inherited. But we can also change text colors in those sections? We can add selectors? We must preserve selectors; can modify existing selectors. For .app-qr-section, we could set background: #151528 and color: #f8fafc. But that changes color only. That's allowed. But might not be enough.

Maybe better: fresh palette with deep purple (#2e1065, #4c1d95), gold (#f59e0b / #d97706), off-white backgrounds (#faf7f2), soft shadows. Keep readability. Since target centered-stage, premium gold or deep purple accent. Use large radius 16-24px. Multi-layer shadows.

Need decide whether to replace var() color references with literals. To ensure change, yes. But there are many. Could define :root at top to override theme vars? That is a custom property value change. But if theme.css loads before/after? This file maybe loaded after. Adding :root could override globally, affecting all pages. Might be acceptable? But risky. However output only this file. If we add :root with new palette, all var usages change. That's efficient. But instructions: selectors must be preserved; adding :root is a new selector. Is that allowed? It says "ONLY the rewritten CSS, preserving ALL selectors and layout exactly". Adding new selectors might violate. Better not add new selectors. Instead replace var() usages with new literal colors. That keeps selectors same. But then if var used for layout (spaces) keep. So replace color vars with literals.

Need map original vars:
--color-primary likely blue #3b82f6. New primary: deep purple #6d28d9? Or gold #d4af37? Target premium gold or deep purple. Use gold accent with deep purple stage. Maybe primary = #7c3aed (violet), primary-dark = #5b21b6, primary-darker = #2e1065, accent = #f59e0b (gold), accent-dark = #b45309. Backgrounds: --color-bg = #f8f7ff, --color-bg-soft = #f3f0ff, --color-bg-muted = #ede9fe? Text = #1e1b2e, text-muted = #5b5570, border = #ddd6fe, border-soft = #e9e5ff, danger = #dc2626. Shadows: multi-layer soft shadows with purple/gold tint.

But if we replace all var(--color-primary) with #7c3aed, etc. Need ensure no var color remains? We can replace. But variables like --gradient-hero, --gradient-icon are custom properties used. If not defined in file, we can't change their value except replace with literal gradients. We can replace var(--gradient-hero) with a new linear-gradient. Same for --gradient-icon. --shadow-sm, --shadow-lg, --shadow-md, --shadow-primary, --transition-fast/base/slow. We can replace with literal shadow/transition values. That is allowed. --space-* keep. --radius-md keep? We can replace with larger value e.g. 16px. --radius-md maybe defined elsewhere; we can replace with 18px. --radius-md used. Good.

Need preserve layout: padding/margin with var(--space-*) keep. But border-radius variables can change to literal. Border-width keep same. If we replace var(--radius-md) with 18px, that's radius only. Good.

Need go through file and rewrite. We can keep comments original. But maybe no markdown. We need output CSS only.

Let's plan palette:
- Stage dark: #0f0f1a (deep indigo)
- Primary accent: premium gold #d4af37? Or deep purple #8b5cf6? Target: "Premium gold or deep purple accent". We can use both: deep purple as primary, gold as accent.
- Primary: #7c3aed (violet)
- Primary dark: #5b21b6
- Primary darker: #2e1065
- Accent: #f59e0b (amber/gold)
- Accent dark: #d97706
- Bg: #f8f7ff
- Bg soft: #f3f0ff
- Bg muted: #ede9fe
- Text: #1e1b2e
- Text muted: #5b5570
- Border: #ddd6fe
- Border soft: #e9e5ff
- Danger: #dc2626

Shadows:
- shadow-sm: 0 2px 4px rgba(46,16,101,0.04), 0 6px 12px -4px rgba(46,16,101,0.08)
- shadow-md: 0 4px 8px rgba(46,16,101,0.06), 0 12px 24px -6px rgba(46,16,101,0.12)
- shadow-lg: 0 8px 16px rgba(46,16,101,0.08), 0 20px 40px -10px rgba(46,16,101,0.18)
- shadow-primary: 0 4px 14px rgba(124,58,237,0.25), 0 12px 28px -6px rgba(124,58,237,0.35)

Gradients:
- hero: linear-gradient(135deg, #0f0f1a 0%, #2e1065 50%, #4c1d95 100%)
- icon: linear-gradient(180deg, #7c3aed 0%, #f59e0b 100%)

Transitions:
- fast: 0.2s cubic-bezier(0.4, 0, 0.2, 1)
- base: 0.35s cubic-bezier(0.4, 0, 0.2, 1)
- slow: 0.5s cubic-bezier(0.4, 0, 0.2, 1)

Radius: use 18px, 24px. Replace var(--radius-md) with 18px. Some hardcoded 4px, 5px -> 12px? Border-radius allowed. Use 12px for code, 16px for scrollbar? Scrollbar thumb radius 5px -> 8px.

Need replace hardcoded colors:
- #fff -> #ffffff or #f8fafc? Keep white.
- #475569 -> #5b5570 (text muted)
- rgba(0,0,0,0.2) -> rgba(15,15,26,0.4) maybe
- rgba(0,0,0,0.3) -> rgba(46,16,101,0.4)
- rgba(0,0,0,0.15) -> rgba(46,16,101,0.2)
- rgba(59,130,246,0.1) -> rgba(124,58,237,0.15)
- #eff6ff -> #f3f0ff
- #94a3b8 -> #a78bfa? scrollbar thumb. Use #a78bfa with hover #7c3aed.
- #555 -> #5b5570
- print colors: #fff, #000, #555. Keep print mostly? We can change to #fff, #000? Print must be readable. Maybe keep #fff, #000. But instruction says change all color values. For print, can change #555 to #444? But must keep print legibility. Change #555 -> #4b5563? Not critical. But "all color values" maybe. We can change #fff -> #ffffff, #000 -> #111111? Print on white, black text. Use #1e1b2e for text? But print background white. We can set body color #111827. But original #000. Change to #111827. a color #1e1b2e. a[href]::after color #4b5563. h1.. color #111827. Fine.

Need ensure selectors exactly same. We can change values inside. Let's go section by section.

Original comments can remain. But if we change var names to literals, may be long. Need be careful with CSS variable fallbacks? We'll just replace.

Let's rewrite.

Need check all original selectors preserved. Comments preserved? We can keep original comments. But output only CSS. Need no markdown fences. We can include original comments? It says no AI marker comments. Original comments okay. But maybe to save tokens, keep. However need ensure first character is first CSS character. If start with comment, that's CSS comment. First character is /? That's CSS. Fine. But maybe no comments? They didn't prohibit original comments. I'll keep them as they are, but I replaced values. Could simplify comments? Better keep original to preserve? The task says only rewritten CSS, preserving all selectors and layout. Comments not selectors. But keeping them is fine. However if we keep comments, output length larger. We have plenty. But need ensure no AI marker comments. Original comments are not AI marker. Fine.

Need double-check all color vars replaced. There were var(--color-primary), --color-primary-darker, --color-primary-dark, --color-text, --color-bg-soft, --color-border, --color-text-muted, --radius-md, --shadow-sm, --transition-fast, --color-bg-muted, --color-danger, --gradient-hero, --transition-slow, --color-accent, --transition-base, --color-bg, --color-border-soft, --shadow-lg, --gradient-icon, --shadow-md, --shadow-primary, --color-accent-dark, --radius-md etc. We replaced.

Check .post-content blockquote border-radius: 0 var(--radius-md) var(--radius-md) 0 -> 0 18px 18px 0. That's radius change allowed.

Check .post-content code border-radius: 4px -> 12px. Allowed.

Check .post-content pre border-radius: var(--radius-md) -> 18px.

Check .post-content table th border: 1px solid var(--color-border) -> #ddd6fe. Border width unchanged.

Check .toc-box border-inline-start: 3px solid var(--color-primary) -> #7c3aed.

Check .post-tags .badge color #475569 -> #5b5570. Allowed.

Check .app-hero-section::before background rgba(0,0,0,0.2) -> rgba(15,15,26,0.4). Allowed.

Check .text-white-50 color rgba(255,255,255,0.65) -> rgba(255,255,255,0.7). Allowed.

Check .qr-card:hover box-shadow 0 15px 40px rgba(0,0,0,0.15) -> multi-layer.

Check .app-install-section .bg-white::before background var(--gradient-icon) -> linear-gradient.

Check .hero-buttons .btn-warning color var(--color-primary-darker) -> #2e1065.

Check scrollbar colors.

Check print #555 -> #4b5563.

Check @keyframes values: opacity, transform unchanged? Allowed to change but no need. We can keep.

Check .animate-fade-in animation: fadeInUp 0.6s ease-out. Original. Animation timing can change but we can keep. Could change to cubic-bezier? But animation-name must stay. We can change duration/timing. Maybe change to 0.5s cubic-bezier(0.4,0,0.2,1). But not necessary. To be more distinct, change to 0.6s cubic-bezier(0.4,0,0.2,1). But animation-name fadeInUp same. .animate-pulse animation: pulse 2s infinite. Could change to pulse 2.4s ease-in-out infinite. Allowed. Let's do that.
