site: a searchable model list, a brio section, and a theme switch

[JustVugg]

What this is

The landing page had drifted. It said eight families run today, listed DeepSeek
and Qwen3 as planned when both have been running for a while, nested DeepSeek
V4.1 Flash inside the V4 card, and did not mention brio mode at all. The models
were a three-column card grid, so every card was as tall as the longest
description in its row.

What changed

The models are a list. One row per family: description, tags, total and
active parameters, the container size, the engine file, and the command that
fetches the weights with a copy button next to it. A search box and five tag
filters narrow the list in place. Nine families now, each linking to the doc
that actually exists for it.

The figures are sourced. Every number comes from the family table in the
README or, where the README is silent, from the model's own card upstream. One
discrepancy surfaced while doing this and is worth a separate look: the README
row for GLM-5.3-Flash says 321B / 40B while Z.ai's card says 320B total and 18B
active, and 40B is also GLM-5.2's figure on the row above. The page uses the
upstream number.

A brio mode section. What the mode is for, with three worked examples
(triage, filling a schema, many questions on one document), the measured
comparison against generating the same answer on qwen36, the request and the
reply of POST /v1/brio, and the calibration figures, which are the actual
point of the mode. It also says plainly where brio does not help.

A light and dark theme, using the mechanism @sparshsingh12312 proposed in
#1551: the same colibri_theme key, the same data-theme attribute set before
first paint so the theme never flashes, the same D shortcut, and the operating
system preference followed only until the visitor chooses for themselves.

Type and mark. Figtree for the page, Bytesized still for the wordmark, and
the favicon is now the mark in its own four colours instead of flat ink.

What did not change

One file, no build step, no framework, no dependency. The filtering, the theme
and the copy buttons are about sixty lines of plain JavaScript at the bottom of
the page. The expert atlas canvas, the hardware numbers and the contributing
section are the same content, restyled.

Checked

• Both themes render, the toggle and the D shortcut switch them, the choice
  survives a reload, and D typed into the search box types a d instead of
  flipping the theme.
• Search, each of the five filters, and a filter combined with a search.
• No console errors, no empty links, no horizontal scroll at 1280 and 1440.

Conflict to resolve

#1551 rewrites the same file, so one of the two has to be rebased on the other.
Its dark-mode design is the one kept here.
