v0.54.10

Added

• Liquid Glass – living drifting backdrop: Added a .lg-backdrop layer with four blurred, slowly drifting color blobs behind the entire app shell — the "liquid" that the glass surfaces now refract. Blob 1 follows --active-module-accent, so the whole ambient subtly recolors per section (e.g. violet on Calendar, teal on Budget), while blobs 2–4 use fixed module tints (shopping, tasks, meals) for variety. The blobs live on the non-scrolling .app-shell (outside the .app-content scroll container), so they neither trigger nor are affected by the iOS/Android blank-screen mitigation (Issue #166). The drift animation honors prefers-reduced-motion (freezes), and prefers-reduced-transparency / prefers-contrast: more hide the backdrop entirely via tokens.
• Liquid Glass – design tokens: Introduced five --lg-* tokens in tokens.css — --lg-blob-opacity (0.4 light / 0.55 dark, 0 in reduced-transparency/contrast), --lg-glass-saturate, --lg-card-radius, --lg-density, and --lg-specular.

Changed

• Liquid Glass – stronger specular on elevated surfaces: The sidebar and bottom navigation now carry an inset top-highlight driven by --lg-specular, per the canonical glass recipe, giving the elevated glass panels a crisper specular edge.
