distinct_server/presentation.py

"""The stylesheet and the palette. Markup lives in :mod:`distinct_server.render`.

One sheet, real tokens, semantic class names, no inline styles. Everything the
product looks like is decided here or in ``render.py``; nothing is decided by
Gradio's generated DOM, which is why the sheet opens by switching most of that
DOM off.

Two constraints outrank every aesthetic decision.

**1. Polish must not launder a missing measurement into a real one.**
An unmeasured run renders with a dash and the words "No data"; it can never
render as ``0`` or ``0.000 J``. An incomplete session total states how many runs
it covers. The two rubric boundaries are separate ``.c-panel`` surfaces, each
carrying an explicit "never added" line, because making them look like one tidy
summary is the exact misreading the rubric forbids. The same rule governs the
grade sheet: ``.c-grade--none`` is a dashed lozenge carrying words, never a
letter, because an absence drawn as a D is a measured poor result that nobody
measured.

**2. WCAG AA, computed rather than assumed.**
Contrast against the canvas ``#FAF9F5``:

===============  =========  ======  ==========================================
Colour           Ratio      AA?     Used for
===============  =========  ======  ==========================================
``#1F1E1A``      15.6:1     pass    body text
``#504D45``      7.6:1      pass    secondary text
``#6C6961``      4.6:1      pass    muted text
``#174F37``      9.3:1      pass    accent text
``#1E6E4B``      6.0:1*     pass    primary button (*white on it: 6.2:1)
``#4E7561``      4.2:1      FAIL    borders, strokes, 24px+ only
``#5E8A73``      3.2:1      FAIL    decorative fill only
===============  =========  ======  ==========================================

The two lighter greens fail AA for body text, so neither is ever used for
body text. Every neutral is warm-grey over ivory; green appears only where
it means something (the action, the selection, the focus).

**Layout: the shell decides its own height.**
The previous sheet locked ``.gradio-container`` and ``.c-shell`` to ``100vh``
with ``overflow:hidden``, then gave ``.c-main`` ``flex:1``. Every pixel of
unused viewport therefore drained into whichever child was allowed to grow,
which is why an empty transcript rendered as an 890px void with three lines of
type floating in the middle of it. Nothing was deciding a height; the viewport
was, and the layout absorbed the difference.

Now the shell is ``min-height:100vh`` in normal document flow, ``.c-main`` is a
two-column grid sized by its content, and the transcript carries an explicit
height range. Leftover viewport falls below the page where it belongs. Every
direct child of ``.c-shell`` shares one padding box, so the header, the notice,
both columns and the tail sit on a single pair of vertical edges rather than the
four the layout had grown.

# ``clamp()`` size, so the letterforms are redrawn for the size rather than
# photographically scaled up. Swap which ``--font-display`` line is live in the

   Gradio puts ``auto-margin`` on most blocks, which resolves to ``margin:auto``.
   On a flex item that is not a neutral default: free space along the main axis
   is handed to auto margins before it is handed to anything else, and this
   column is a flex column, so every block took a share of whatever the taller
   middle column had left over. The symptom was a gap that moved: about 8px on
   an empty page, and about 200px of nothing between the worker picker and the
   worker card once a conversation had made the middle column tall. Nothing was
   missing and nothing was broken, which is why it read as sloppiness rather
   than as a fault.

   The gap between blocks is this column's own ``gap``, and it is the same
   whatever is beside it. The credit keeps its ``margin-top:auto`` because
   pinning it to the bottom is deliberate. */

   it, and it hangs off both sides of a box that an ancestor had set to

   the main thing on offer, which it is not: it is one affordance among three.

   The caption is text nodes rather than elements, so it cannot be selected and

   once, and the wanted word is restored on the pseudo-element at a real size.
   The icon is an element and gets its size back explicitly. Dropping still

   to the whole control, which also caught the preview's own undo and clear

# ---------------------------------------------------------------------------
# WHY THE SHEET IS POST-PROCESSED INSTEAD OF WRITTEN WITH !important BY HAND
#
# Gradio ships a Tailwind-derived reset scoped to a version-stamped container
# class: rules like ``.gradio-container-6-24-0 *``, ``.gradio-container-6-24-0
# [type="radio"]`` and ``.gradio-container-6-24-0 p``. A plain component class
# such as ``.c-os__radio`` is specificity (0,1,0); those are (0,1,1) and (0,2,0).
# They win. Worse, the sheets are injected in a different order on Spaces than
# in local dev, so a rule that survives on a laptop can be flattened in
# production — the exact failure that shipped a page which "looks identical"
# after a redesign.
#
# An audit of the live Space found 43 declarations losing this way: numbered
# steps drew Gradio's list markers *and* our own badges, the OS-switch radios
# kept their 16px box instead of collapsing to 1px, copy buttons kept the
# native button appearance, and paragraph margins throughout picked up the
# prose reset's 8px.
#
# Two earlier attempts fixed instances — first ``border``, then ``color`` —
# by hand. Both regressed the moment a new rule was added, because the next
# author has no reason to know which properties Gradio happens to reset. So
# the guarantee is mechanical instead: every declaration in a rule that styles
# one of our own ``.c-`` components is marked important at import time.
#
# This does not change how our own rules rank against each other. When two
# ``.c-`` rules both become important, specificity and then source order decide
# exactly as before, so state rules (``.c-libcard.is-on``), pseudo-class rules
# (``:hover``) and the mobile ``@media`` block at the end of the sheet all keep
# winning over the base rules they were written to override.
#
# Rules that deliberately target Gradio's own DOM are left alone: they are
# written with explicit ``!important`` where they need it, and hardening them
# blindly would freeze parts of the widget tree we only mean to nudge.
