 - Dual-Mode Theme Architecture (双形态主题架构与材质光影精细化):
   - **Base Design System Tokens (`--amb-*`)**: Scoped on `:root` and overridden under `.theme-abyssal-scarlet`. Defines unified background, panel, card, text, border, and control radii tokens (`--amb-radius-control: 6px`, `--amb-radius-card: 10px`, `--amb-radius-panel: 12px`).
-  - **Normal Mode (Default / 标准中性黑曜石图书档案馆模式)**: Restrained, clean, neutral dark obsidian (`#141519` / `#1c1e24` / `#24262e`) styling; overlaid with the "Anime Celestial Library Archive" AI Concept Art Watermark (`assets/archive_library_bg.webp`) on `#anomalous-content::before` at `0.08` opacity with `mix-blend-mode: luminosity`, creating a grand, atmospheric anime archival hall ambiance while ensuring zero interference with model covers; silver-white primary button (`#D7D9E0` with `#15171C` text); neutral card borders and restrained left-accent category lines.
+  - **Normal Mode (Default / 标准中性黑曜石图书档案馆模式)**: Restrained, clean, neutral dark obsidian (`#0b0d13` / `#141519` / `#1c1e24`) styling; overlaid with the "Anime Celestial Library Archive" AI Concept Art with glowing holographic magic circles, golden blueprint wireframes, and constellation starmap textures (`assets/archive_library_bg.webp`) at `0.65` opacity with radial dark vignette, visible through the transparent grid background (`#anomalous-grid { background: transparent; }`), creating a distinct, majestic anime archive hall atmosphere while ensuring model covers remain clear and high-contrast; silver-white primary button (`#D7D9E0` with `#15171C` text); neutral card borders and restrained left-accent category lines.
   - **Abyssal Scarlet Easter Egg Mode (`.theme-abyssal-scarlet` / 深海血族彩蛋领域 - 丝绒与暗血轻量质感)**: Strictly scoped under `.theme-abyssal-scarlet`; eliminates all cheap neon outer glows; deep gothic velvet backgrounds (`#161014` / `#21171d` / `#2b1e26`), razor-sharp crimson (`#dc143c`) and antique gold (`#b38728`) borders, crimson primary buttons (`#87384E` with `#FFF5F7` text), and concept art backdrops `assets/abyssal_scarlet_mansion.webp` and `assets/abyssal_bg_concept.webp`.
   - **Three-Tier Button Architecture**: Unifies button morphology across primary, secondary/ghost, and auxiliary actions. Primary buttons (`.anomalous-btn-primary`, `.anomalous-recipe-btn-primary-action`) feature solid fills, 32px height, 6px border-radius, clean SVG icons, and zero pseudo-element clutter (purged legacy `::before` diamonds, `::after` gradient lightbars, text-shadows, and heavy glows); secondary ghost buttons (`.anomalous-btn-ghost`) feature subtle borders and panel backgrounds; auxiliary action buttons provide clear, non-distracting tool semantics.
