+# omarchy-theme-set-obsidian: Bootstrap and update Omarchy theme for Obsidian
+#
+# - Ensures registry at ~/.local/state/omarchy/obsidian-vaults
+#   - If missing/empty, bootstraps by scanning ~/Documents/*/.obsidian and ~/Dropbox/*/.obsidian
+# - For each valid vault:
+#   - Ensures .obsidian/themes/Omarchy/{manifest.json, theme.css}
+#   - Updates theme.css (uses current theme’s obsidian.css if present; otherwise generates -- see below)
+
+# Theme automagic generation logic:
+#
+# - Background/foreground: read from ~/.config/omarchy/current/theme/alacritty.toml [colors.primary]
+#   (background/foreground). Fallbacks: bg=#1a1b26, fg=#a9b1d6. Compute bg brightness for light/dark handling.
+# - Palette extraction: collect colors from Alacritty (primary/normal/bright/dim/selection), Waybar (@define-color),
+#   and Hyprland (col.*_border; rgba->hex). Normalize, dedupe, and count frequencies.
+# - Slot ordering: remove bg/fg, sort remaining colors by frequency, then fill 13 slots by cycling. Map slots to:
+#   h1–h6, links, inline code, marks, interactive accent, blockquote border; muted/faint use border color.
+# - Code colors: code background = closest color to bg (Euclidean RGB); if none, make a subtle bg variant (+/− RGB).
+#   code foreground = closest color to fg; fallback #e0e0e0.
+# - Border color: from btop.theme theme[div_line]; else blended mix biased toward bg (≈ (bg+fg)/3).
+# - Selection: from Alacritty [colors.selection] (background/text), honoring CellForeground/Background.
+#   If missing, background = 75% bg + 25% fg; text chosen for contrast vs selection background.
+# - Fonts: monospace from Alacritty [font] or fontconfig monospace; UI font from fontconfig sans-serif.
