In `@src/patternfly/components/FormControl/form-control.scss`:
- Around line 21-24: The new custom property
--#{$form-control}--TransitionDuration is introduced but not used everywhere
(the duration is still hardcoded/bypassed in the other rule), so update the
rules that set transition-duration to instead reference
var(--#{$form-control}--TransitionDuration); locate occurrences of
--#{$form-control}--TransitionDuration and replace any direct/two-token duration
usages (the block around the other transition declaration) so all transition
declarations use var(--#{$form-control}--TransitionDuration) as the single
source of truth (also update the duplicate occurrences noted around the 168-171
block).
- Line 454: The icon's transition is inheriting from
.pf-v6-c-form-control__utilities (which has no transition) causing snap changes;
update the stylesheet by either adding "transition: inherit;" to the
.pf-v6-c-form-control__utilities rule or by giving .pf-v6-c-form-control__icon
explicit transition longhand properties (e.g.,
transition-property/transition-duration/transition-timing-function) so the
.pf-v6-c-form-control__icon animates consistently with the root
.pf-v6-c-form-control.

In `@src/patternfly/components/Button/button.scss`:
- Around line 942-945: The background shorthand currently always composes
disabled background with --#{$button}--BackgroundSurface which forces a tint
onto transparent variants like --#{$button}--m-plain--disabled--BackgroundColor:
transparent; change the rule that sets background (the line using
var(--#{$button}--disabled--BackgroundColor)
var(--#{$button}--BackgroundSurface)) so the surface is overridable—e.g. use the
surface custom property with a fallback of none or conditionally omit it—so
plain/transparent disabled buttons can set --#{$button}--BackgroundSurface: none
(or leave it unset) and stay transparent; update the background declaration
referencing --#{$button}--disabled--BackgroundColor and
--#{$button}--BackgroundSurface accordingly.

In `@src/patternfly/components/FormControl/form-control.scss`:
- Around line 309-315: The disabled state currently sets
--#{$form-control}--before--BorderStyle and
--#{$form-control}--after--BorderStyle to none which removes the pseudo-borders
and prevents the border transition; instead keep the border style (don’t set
them to none) and set the corresponding border-color variables to the
disabled/transparent values so the outline can animate (update usage around
.pf-m-disabled and the CSS vars --#{$form-control}--before--BorderStyle,
--#{$form-control}--after--BorderStyle and the matching
--#{$form-control}--before--BorderColor / --#{$form-control}--after--BorderColor
or their --m-disabled counterparts).

- Around line 25-28: The child transition custom properties for the form control
components (e.g., --#{$form-control}__control--TransitionDuration,
--#{$form-control}__control--TransitionProperty, and their __icon and
__toggle-icon counterparts) are set to 0s/none which disables child animations;
update these child variables to inherit or reference the wrapper transition
variables (the wrapper's transition timing/duration/property variables) so child
parts (select background, disabled toggle-icon color, etc.) follow the wrapper
animation, and remove hard-coded 0s/none defaults in the blocks that define
__control, __icon, and __toggle-icon (also apply same change to the other
occurrences covering the ranges noted) so children animate smoothly with the
wrapper.

Duplicate comments:
In `@src/patternfly/components/FormControl/form-control.scss`:
- Around line 25-28: The nested control/icon transition token defaults are
invalid/too-zeroed (e.g.,
"--#{$form-control}__control--TransitionTimingFunction: auto" and 0s/none for
delay/duration/property) so child longhands snap; change the nested tokens in
form-control.scss to reference the wrapper's real transition tokens (e.g.,
replace "--#{$form-control}__control--TransitionDelay",
"--#{$form-control}__control--TransitionTimingFunction",
"--#{$form-control}__control--TransitionDuration",
"--#{$form-control}__control--TransitionProperty" with var(...) lookups of the
parent tokens like "--#{$form-control}--TransitionDelay",
"--#{$form-control}--TransitionTimingFunction" etc., and use a valid default
timing-function (e.g., ease) or a fallback in the var(...) so computed values
remain valid); apply the same change pattern to the other occurrences noted
(around lines 142-145 and 162-165) so child controls inherit/propagate the
wrapper's real transition values instead of 0s/none or the invalid "auto".

- Around line 168-171: Update the transition declarations in the form-control
styles so they also apply to the border-rendering `&::before` and `&::after`
pseudo-elements, allowing their `border-color` changes to animate. Exclude
`border-style` from the transition to prevent animating the disabled-state
switch to `none`.

- Around line 301-304: Update the disabled-state &::before and &::after rules in
the form-control styles to use the existing
--#{$form-control}--m-disabled--after--BorderColor token rather than hardcoding
transparent, preserving consumer overrides for both pseudo-elements; remove the
token only if it is intentionally no longer needed.
