+# Voice Constant, Tone Flexes
+
+The core mental model for brand voice enforcement: voice is constant, tone flexes by context.
+
+## The Distinction
+
+**Voice** is WHO the brand is — personality, values, identity. It never changes regardless of channel, audience, or content type. Think of it as the brand's character.
+
+**Tone** is HOW the brand speaks in a given moment — formality, energy, technical depth. It adapts to context the way a person adjusts their tone when speaking to a friend vs. a CEO vs. a large audience.
+
+## Voice Constants: "We Are / We Are Not"
+
+The "We Are / We Are Not" table is the anchor of brand voice. It defines the brand's personality in paired attributes — what the brand IS and the boundary it should never cross.
+
+### Structure
+
+The table below is an illustrative example. During enforcement, use the "We Are / We Are Not" table from the user's own brand guidelines.
+
+| We Are | We Are Not |
+|--------|------------|
+| **Confident** — we know our product and stand behind it | **Arrogant** — we never talk down to prospects or dismiss alternatives |
+| **Approachable** — we make complex topics feel manageable | **Casual or sloppy** — approachable doesn't mean unprofessional |
+| **Direct** — we get to the point quickly and clearly | **Blunt or aggressive** — directness includes empathy |
+| **Data-driven** — we support claims with evidence | **Dry or academic** — data tells stories, not lectures |
+| **Innovative** — we push boundaries and challenge status quo | **Hype-driven** — innovation is real, not buzzwords |
+
+### How to Use During Enforcement
+
+For every piece of content:
+1. Check each "We Are" attribute — does the content reflect this?
+2. Check each "We Are Not" boundary — does the content avoid crossing it?
+3. If a boundary is crossed, revise the specific passage
+4. If an attribute is missing, find a natural place to express it
+
+Not every attribute needs to appear in every piece of content. Prioritize the 2-3 most relevant attributes for the content type and audience.
+
+## Tone Flexes: The Three Dimensions
+
+Tone adjusts along three independent dimensions:
+
+### 1. Formality
+How formal or casual the language is.
+
+| Level | Signals | When |
+|-------|---------|------|
+| High | Complete sentences, industry terminology, structured format | Proposals, RFPs, enterprise comms |
+| Medium | Clear and professional but conversational | Most emails, presentations, blog posts |
+| Low | Casual language, contractions, personality shows through | Social media, internal comms, Slack |
+
+### 2. Energy
+How much enthusiasm, urgency, or dynamism the content conveys.
+
+| Level | Signals | When |
+|-------|---------|------|
+| High | Active verbs, short sentences, exclamation-worthy excitement | Product launches, cold outreach hooks, social media |
+| Medium | Steady pace, balanced between informative and engaging | Discovery content, follow-ups, case studies |
+| Warm | Empathetic, supportive, understanding | Customer success, objection handling, bad news |
+| Low | Measured, thoughtful, deliberate | Legal language, policy docs, sensitive topics |
+
+### 3. Technical Depth
+How much domain expertise or technical detail is included.
+
+| Level | Signals | When |
+|-------|---------|------|
+| High | Technical terminology, architecture details, specs | Technical audience, implementation proposals, API docs |
+| Medium | Industry terms explained when needed, features described clearly | Mixed audience, product demos, mid-funnel content |
+| Low | Outcome-focused, benefits over features, no jargon | Executive audience, cold outreach, social media |
+
+## Tone-by-Context Matrix
+
+| Context | Formality | Energy | Technical Depth | Key Principle |
+|---------|-----------|--------|-----------------|---------------|
+| Cold outreach | Medium | High | Low | Hook fast, earn attention |
+| Discovery calls | Medium | Medium-High | Medium | Ask more than tell |
+| Demo / presentation | Medium-High | High | High | Show, don't just describe |
+| Enterprise proposal | High | Medium | High | ROI and precision |
+| Follow-up email | Medium | Medium | Low-Medium | Add new value each touch |
+| Social media | Low-Medium | High | Low | Brevity and personality |
+| Customer success | Medium | Warm | Medium | Empathy and competence |
+| Internal comms | Low | Medium | Varies | Authentic, less polished |
+
+## Common Enforcement Mistakes
+
+1. **Applying all voice attributes at maximum intensity** — Not every attribute needs to shine in every sentence. Let 2-3 lead for the content type.
+2. **Confusing voice with tone** — If the user asks for "casual" content, adjust TONE (lower formality, higher energy). Don't change VOICE (the brand's personality stays the same).
+3. **Rigid enforcement over natural flow** — Guidelines are principles, not a checklist. Content should feel natural, not mechanically assembled.
+4. **Ignoring the audience** — The same voice can sound very different to a CTO vs. a VP of Sales. Tone flexes handle this.
