-Light theme values are taken directly from `mock-v2-light.html` `:root` block. Dark theme values will be derived with inverted lightness and reduced saturation (the existing `mock-v2-dark.html` is considered "too colorful" — dark theme should be more muted).
+**Semantic color naming convention:** Components use semantic variant names that map to tokens:
+- `primary` → `--amber` tokens
+- `success` → `--success` tokens
+- `warning` → `--warning` tokens
+- `error` → `--error` tokens
+- `running` → `--running` tokens (teal, for in-progress/active states)
+
+This convention applies to all components with color/accent props (Card, Badge, StatusDot, FilterPill, InfoCallout, etc.). No mixing of token-level names (`teal`, `green`) with semantic names.

+Light theme values are taken directly from `mock-v2-light.html` `:root` block.
+
+**Dark theme strategy:** The existing `mock-v2-dark.html` is considered "too colorful" and will not be used as-is. The dark theme will be a muted redesign that:
+- Reuses the same token names as light (no separate `--bg-deep` / `--bg-base`)
+- Inverts lightness and reduces saturation
+- Drops glow tokens (`--amber-glow`, `--success-glow`, etc.) — these are not canonical
+- Uses the same `--radius-sm: 5px` value (the dark mock's 6px was unintentional)
+- All dark overrides go in a single `[data-theme="dark"]` block remapping the same variable names
 
 ### 3.2 Deterministic Color Hashing
 
 A `hashColor(name: string)` utility generates consistent HSL colors from any string:
 
-1. Compute SHA-256 of the input name
-2. Extract first 2 bytes → map to hue (0-360)
+1. Compute FNV-1a hash of the input name (synchronous, fast, good distribution)
+2. Take hash modulo 360 → hue angle
 3. Light theme: `hsl(hue, 45%, 92%)` background, `hsl(hue, 55%, 35%)` text
 4. Dark theme: `hsl(hue, 35%, 20%)` background, `hsl(hue, 45%, 75%)` text
 
+FNV-1a is chosen over SHA-256 because it is synchronous (no `crypto.subtle` async), lightweight (~10 lines), and provides sufficient distribution for color bucketing.
+
 Used by `Badge` and `Avatar` components when no explicit color variant is provided.
