/* Fallback pattern used throughout this file:
 * Duplicate declarations (e.g., border-color, background) are intentional progressive enhancement.
 * The first line uses a static rgba() value as a fallback for browsers that don't support color-mix().
 * The second line uses color-mix() referencing --local-llm-accent / --local-llm-line etc.
 * The rgba() fallbacks were computed to match the color-mix() output when --local-llm-accent = #00e5ff
 * and --local-llm-line = rgba(255, 255, 255, 0.08). Example: color-mix(in srgb, #00e5ff 45%, rgba(255,255,255,0.08))
 * ≈ rgba(0, 229, 255, 0.45). The loading variant (line ~509) uses 58% against rgba(255,255,255,0.2) which
 * resolves to ≈ rgba(0, 229, 255, 0.58). These are visually matched, not mathematically identical. */
