Rename .scss → .css and remove sass dependency (Phase 9-10)

Rename all 93 .scss files to .css, inline remaining Sass-only
syntax (// comments → /* */, arithmetic → pre-calculated values,
local $vars → hardcoded), update JS entry point imports, remove
sass-loader from webpack, remove sass/sass-loader/stylelint-config-
standard-scss packages, and clean up extraction scripts.

Convert mastodon flavour SCSS to CSS custom properties (Phase 7)

Replace $var with var(--var) across all 23 mastodon/*.scss files + mailer.scss.
Inline avatar/search mixins, unroll @each/@for, hardcode hex-color() in data URIs.
Merge pre-calculated properties into variables.scss :root blocks for all 3 themes.
Fix theme import order, delete _mixins.scss and temporary properties files.

Convert glitch component SCSS to CSS custom properties (Phase 5+6)

Replace $var with var(--var), inline all mixins, unroll @each/@for,
convert color functions to pre-calculated properties. Merge properties
into variables.scss :root blocks, fix theme import order for CSS cascade.

Convert 17 SCSS files to CSS custom properties (Phase 3-4)

Replace $variables with var(--custom-properties), pre-calculated
color functions with themed custom properties, and unroll Sass
control flow (@each, @for, @extend) into plain CSS. Files keep
.scss extension during transition as index.scss still imports them.

Build: split CSS/SCSS webpack rules + generate CSS custom properties

- Split webpack css rule into separate .css and .scss rules so pure
  CSS files skip sass-loader (Phase 1)
- Generate properties.css for dark/light/contrast themes with all
  pre-calculated color values as CSS custom properties (Phase 2)
- Add extract-colors.js helper script for color value generation
