YouTube: Maintainability issues

### Is there an existing issue outlining your problem? - [x] I have searched the existing issues and they do not solve my problem. ### What userstyle are you seeing the problem on? lbl:youtube ### Describe your problem. As mentioned at https://github.com/catppuccin/userstyles/issues/2219#issuecomment-4269138949, YouTube as it migrates towards a styling solution matching modern Google Search is become almost impossible to maintain. This is a subsection of some of the new hashed CSS variables. ```css [dark] { --t7f4f2c6d54836ce0: rgba(255,255,255,0.1); --t7d8b8e5ee291aec0: rgba(0,0,0,0.05); --t4726c68ef6d7b08f: rgba(0,63,13,0.6); --tf0a0d1154827847f: rgba(124,41,0,0.6); ... ``` ```css .ytChipShapeActive { background-color: var(--t1405e70a39276293); color: var(--t6216186c28b3834b); } ``` ```css html:not(.style-scope) { --paper-dialog-background-color: var(--t518e925f61bdcb91); --paper-listbox-background-color: var(--t518e925f61bdcb91); --paper-listbox-color: var(--tffc2fd3a644f6275); } ``` While these updates also introduced new YouTube system variables (`--yt-spec-*`), the hardcoded variables are not being bound to these and instead are being resolved at SCSS build time. It should be determined how we should move forward from this.
