main.min.css was 158.2 KB — a third of the entire 484 KB site, and
render-blocking on every page. It is now 94.4 KB, 40% smaller, with
no visual change anywhere.

Where the weight was

Measured by building with and without each piece:

	size
whole stylesheet	158.2 KB
your own SCSS	33.3 KB (21%)
Bootstrap output	124.8 KB (79%)

Browser CSS coverage across seven pages covering every layout found
34.4 KB ever used. Your bespoke SCSS is 33.3 KB and essentially all of
it is live, so the unused portion was almost entirely Bootstrap.

What went

pagination — the markup never names it. Exact class counts across
the built site: .pagination 0, .page-item 0, .page-link 0.

grid — .row 0, .col-* 0. The invite-row and join-row in
home.html and docs.html are ours; an earlier substring grep of mine
mistook them for Bootstrap's, which is why the counts here are anchored
to whole class names.

The utility matrix — 68.9 KB generating a class for every value of
every utility. The markup wears eighteen:

bg-dark  d-flex  d-md-flex  d-none  flex-column  flex-shrink-0  h-100
mb-2  mb-4  mb-md-0  me-auto  mt-auto  my-0  py-0  py-3
text-body-tertiary  text-center  w-100

$utilities is now narrowed to the thirteen groups those come from,
before utilities/api reads it. Adding a utility later means adding a
line there first — a papercut, and also a guardrail.

map.get needs sass:map, and a @use must precede every @import,
so that one line sits at the top of the file.

What stayed, and why

containers (.container-fluid on 21 pages), helpers (.fixed-top
on 21), nav/navbar (.nav-link and .nav-item 168 each), plus
reboot and root.

Checked

• nps test — all verify tasks pass.
• All 18 utility classes plus .container-fluid, .fixed-top,
  .navbar, .nav-link, .nav-item, .btn and .btn-primary still
  resolve to rules in the built CSS.
• 9 pages × 2 viewports, all 18 screenshots pixel-identical to the
  build before this change — home, news, about, docs, license, a
  handbook page, a news post, 404 and a security doc, at 1280px and
  390px.
• The mobile drawer still opens on one tap in WebKit, with
  aria-expanded and inert correct, and closes again. No page
  errors.

Left on the table

buttons costs 10.0 KB and styles a single .btn on /404/.
Replacing it with a bespoke rule would take the stylesheet to roughly
84 KB, but that changes how that button looks unless matched carefully,
so it is not in this PR.

Summary by CodeRabbit

• Performance
  • Reduced the amount of unused styling included in the application by limiting Bootstrap utilities and removing unnecessary pagination and grid styles.
