+The guard fails on maryUI tags, daisyUI classes, colours the theme does not declare, unknown Material Symbol names and Blade directives written inside component tags. It also fails on everything 2.0 cleared, and every line names the replacement: Tailwind's breakpoint prefixes (`sm:` and `md:` → `medium:`, `lg:` → `expanded:`, `xl:` → `large:`, `2xl:` → `extra-large:`, `max-` likewise), its radius (`rounded-lg` → `rounded-corner-lg`), shadow (`shadow-md` → `shadow-elevation-2`), text size, weight, leading and tracking (`text-sm`, `leading-6`, `tracking-wide` → a `type-*` style, `font-medium` → a `type-emphasized-*` style), easing and duration (`ease-in-out` → `ease-standard`, `duration-300` → a `duration-(--md-sys-motion-…-duration)` with the easing it pairs with), and a colour written as a value rather than a role (`bg-[#1d7afc]`, `text-[rgb(…)]`, `border-[color-mix(…)]`).
+
+Two checks are opt-in: `forbidAbsolutes()` also fails on `bg-white` and `text-black` (M3's white is `surface-container-lowest`), and `forbidOpacityInk()` on opacity used as emphasis (`text-on-surface/60` → `text-on-surface-variant` or `text-outline`). M3 reserves 38 % on content and 12 % on a container for the disabled state, which is what the package's own components use them for, so neither is on by default.

 It fails on maryUI tags, daisyUI classes, colours the theme does not declare, unknown symbol names and Blade directives written inside a component tag (where they do not compile), with `path:line` for each.
 
+It also fails on every value the theme cleared, and names the replacement on the same line:
+
+| Written | Use |
+| --- | --- |
+| `sm:`, `md:` (and `max-sm:`, `max-md:`) | `medium:` (`max-medium:`) |
+| `lg:`, `xl:`, `2xl:` | `expanded:`, `large:`, `extra-large:` |
+| `rounded-lg`, `rounded-t-2xl`, `rounded-full` | `rounded-corner-lg`, `rounded-t-corner-xxl`, `rounded-corner-full` |
+| `shadow-sm`, `shadow-md` … `shadow-2xl` | `shadow-elevation-1` … `shadow-elevation-5` |
+| `text-sm`, `leading-6`, `tracking-wide` | a `type-*` style, which sets the three together |
+| `font-medium`, `font-bold` | a `type-emphasized-*` style |
+| `ease-in-out`, `ease-linear` | `ease-standard`, or an `ease-spatial-*`/`ease-effects-*` |
+| `duration-300` | `duration-(--md-sys-motion-…-duration)`, paired with its easing |
+| `bg-[#1d7afc]`, `text-[rgb(…)]`, `border-[color-mix(…)]` | an M3 role |
+
+`forbidAbsolutes()` adds `white` and `black` (M3's white is `surface-container-lowest`, its ink an `on-` role) and `forbidOpacityInk()` adds opacity as emphasis (`text-on-surface/60` → `text-on-surface-variant` or `text-outline`). Both are off by default: M3 reserves 38 % on content and 12 % on a container for the disabled state, and the package's own components are written with those two opacities.
+
 ## Conventions
 
 - Components are anonymous Blade components: `<x-name>` without a prefix, or `<x-{prefix}::name>` when `config('livewire-material.prefix')` is set; `<x-livewire-material::name>` always works.
