When the chevron opens the details, the To/Cc rows pop up as an
absolutely-positioned panel anchored to the bottom of the meta
block — with bg, border, rounded corners and a shadow. Nothing
in the rest of the header reflows: From row stays put, the action
cluster stays put, the email body content stays put. This kills
all the height-/spacing-jump quirks the inline-expanded design
was fighting.
- .email-reader-meta .recipient-chip drops max-width and overflow
truncation so the full name renders in each chip. The parent
.recipient-chips span already has overflow-x:auto, so users can
swipe horizontally to reveal any chip whose tail is clipped off
the right edge of the row.
- Strong (From: / To: / Cc:) labels get explicit white-space:nowrap
+ flex-shrink:0 so they never truncate even when the row is
squeezed to its minimum width.
Firefox mobile rendered the backdrop-filter:blur + var(--panel)
combination on the slide-out sidebar as semi-transparent, so the
chat input bar's selected-model label (e.g. "minimax") was
visible behind the drawer. Force background:var(--panel) and
backdrop-filter:none inside the mobile @media block.
The left-edge gradient fade was likely the source of the perceived
shadow under the icons on mobile. Forced background:none and the
matching padding-left:0 on mobile so the cluster reads as bare
icons without any soft edge.
Was only the date moving — the expanded card had a more-specific
`padding: 4px 0 6px` shorthand on the title row that zeroed out
the padding-left from my earlier nudge. Added the expanded-card
selector to the padding-left:4px rule so the title now lines up
with the meta line in both list and expanded states.
Was using flex-wrap:wrap on the From row, which let the chip span
flip onto a new row below From: when the available width briefly
dropped — then snap back as the chip span's overflow-scroll kicked
in. Switching to flex-wrap:nowrap keeps the label glued to the
chip; the chip span shrinks/scrolls horizontally instead.
In docked mode the header already reserves vertical space for the
absolute action cluster, so the To/Cc details fit without any
height tradeoff — force [hidden] open and hide the chevron toggle
so the recipients are always visible there.
Was From→To = 0 (meta gap 2 + details margin-top 0) while To→Cc
was 6 (details gap). Set details gap to 2 in docked too so all
three meta rows have the same vertical distance. Dropped the
per-row margin-top:4 docked override since spacing now comes
entirely from gaps.
Docked header is flex-direction:column, and the base
align-items:flex-start was sizing the meta to its chip width and
parking it at the left — the absolute cluster's right:0 then
landed at the meta's right edge in the middle of the pane.
align-items:stretch makes meta fill the header width so right:0
hits the actual right edge.
Dropped the docked-specific overrides (cluster flowing below meta,
padding-right:0, header min-height:0). The same container-query
rules drive both: cluster floats top-right and wraps to 2 rows
when the reader width crosses 600px, snaps to overlay below 380px.
Docked pane width is just another container width.
1. Moved the min-height from .email-reader-header to .email-reader-meta
(92px) inside the <600 container query. Targeting the container
itself in its own @container rule was flaky; using a descendant
that affects the parent's intrinsic height works reliably.
2. Dropped the margin-top:0 reset on the cluster in the <380 overlay
rule — that was clearing the base -7px lift and sliding the
cluster ~7px downward at the breakpoint. Now both states use the
same -7px lift so the visual position is stable across the
transition.
Dropped the @media(769px) from-row min-height + align-items:center
and the strong > top:-2px nudge — leftovers from the grid layout
that were forcing extra height and label offsets the block-flow
meta doesn't need.
Consolidated docked overrides into a single flat block (no @media
wrapper) and merged the two .email-reader-meta declarations into
one. Same visual result, much less competing CSS to debug.
When the cluster wraps to 2 rows (44 + 4 gap + 44 = 92px tall), it
was peeking out below the header bottom because min-height stayed
at 60px (only ~44px of cluster room). Bumped min-height to 108px
inside the same <600 container query so the wrapped cluster sits
fully inside the header with 8px breathing room top + bottom.
Replaced the grid layout (which made From row height depend on
cluster height, causing To/Cc to shoot up or down at the wrap
breakpoint) with a plain block stack:
- meta = position:relative block
- From row + details = natural block flow with padding-right
reserving space for the absolute cluster on the right
- cluster = position:absolute top-right, width changes per
container query (308px wide / 158px narrow / 180px overlay)
- padding-right tightens from 320px → 170px → 0 as the cluster
shrinks and finally goes overlay
- details margin-top dropped from -10px to 0 since there's no
grid row gap to compensate for
To/Cc now hugs From with no jumps when the cluster wraps or
overlays.
Removed the medium-mode -12px details margin compensation — it
under/over-shot depending on grid row sizing. Replaced with a
:has() rule: when the user expands To/Cc, the From row gets
min-height 92px (matching the cluster's 2-row max height). Row 1
becomes the same size whether the cluster is 1 row (wide) or 2
rows (narrow), so resizing across the 600px wrap breakpoint no
longer makes To/Cc shoot up 4px.
When the cluster snaps to absolute overlay at <380px, it stops
contributing to grid row sizing — row 1 was collapsing to the From
row's natural height, which made the To/Cc details slide upward and
left the floating cluster visually misaligned against them. Setting
min-height:88px on the From row inside the same container query
holds row 1 at the cluster's two-row height so nothing jumps.
Was fanning out to 3 rows because the 152px max-width (3 icons +
2 gaps exact) had no slack — subpixel rounding could push the
third icon over and trigger another wrap. Bumped to 158px in the
in-grid mode (600px breakpoint) and 180px in the absolute-overlay
mode (380px breakpoint, where the 22px padding-left from the
gradient fade was also eating into the 3-icon row width).
Was wrapping into 4+ rows at narrow widths because the cluster's
grid column could shrink below the 3-icon cap. Set both min-width
and max-width to the 3-icon row width and justify-self:end on the
cluster so the icons stay glued to the right edge instead of
sliding toward the middle when the cluster is wider than its
content.
The 600px / 380px breakpoints were @container docpane queries but
the email reader isn't inside a docpane container — they never
fired and the cluster wrapped to 3+ rows at narrow widths. Added
container-type:inline-size + container-name:emailreader on
.email-reader-header and switched the queries to that container,
so the 2-row cap now actually applies.
Three-step shrink:
1. > 600px pane: cluster sits in col 2 as 1 row of 6
2. 380-600px pane: cluster capped at 3-icon width so wrapping
stops at 3 + 3 (max 2 rows) — chips share width with the 2-row
cluster instead of multiplying into 3+ rows
3. < 380px pane: cluster snaps to absolute overlay with left-edge
box-shadow, still capped at 3-icon width so it's the same 2-row
shape but floating above the truncated chips
Grid tracks now:
- col 1: minmax(60px, 250px) — chip natural width capped at 250px,
with the 60px (4 char) floor enforced on From / To / Cc alike
- col 2: minmax(48px, 1fr) — takes the rest, shrinks first when
the pane narrows
Removed the hard max-width on the action cluster so on wide panes
it stays as one row of 6. Once col 2 shrinks below the 1-row width,
flex-wrap kicks in and the icons re-stack to 3+3. Chips only start
to shrink past that point.
- Action cluster's max-width is calc(48*3 + 4*2) so the 6 icons
always lay out as 3 top / 3 bottom by default.
- When the pane narrows the chips in col 1 shrink first (with 60px
min so 4 chars + ellipsis stay visible).
- At <380px the cluster snaps to absolute overlay with a left-edge
box-shadow so it reads as floating above the truncated chip.
Two-step shrink behavior:
1. As the pane narrows, the action cluster (max-width:50% of meta)
wraps to a 2-row icon stack first
2. Then the recipient chip span starts overflow-scrolling, but
keeps a 60px min-width (~4 chars) so the first chars of the
sender/recipient name stay visible
Previously only the From row affected the action cluster's column
width — To/Cc detail rows spanned both columns and ignored the
cluster. Now:
- meta-details lives in col 1 only so the To/Cc chips shrink
together with the From chip when the pane narrows
- action cluster spans rows 1 and 2 so its width is set by the
widest col-1 content; a long To/Cc list triggers the wrap to a
2-row icon stack just like a long From sender does
Meta switched to CSS grid in undocked mode:
- row 1, col 1: From row (label + chip + chevron)
- row 1, col 2: action cluster
- row 2, span: To/Cc details
The cluster shrinks alongside the chip and flex-wraps into a 2-row
icon stack before crowding the chip. At very narrow pane widths
(< 380px via @container docpane) it snaps back to absolute overlay
so From: still fits.
Docked mode overrides meta back to flex column so the cluster
flows naturally last — under From, and under To/Cc when expanded.
Was rendering as a transparent ghost — From chip / sender text bled
through the gaps between icons. Added a left-fading gradient
backed by var(--bg) so the cluster reads as an opaque overlay
while chips poking out from underneath blend smoothly into its
left edge.
- Window-level recipient-chip click handler now bails if the chip
is inside .email-reader-meta — the per-reader handler still
toggles the expanded-address view on click.
- The from-sender (magnifying glass) search button SVG is now
tinted with var(--accent-primary) so it stands out as a deliberate
search action against the neutral Reply / Forward / etc icons.
Moved the action cluster out of the From row to a sibling of meta
inside .email-reader-meta. Undocked: cluster is absolute-positioned
top-right of the header so it overlays the From line as before.
Docked: cluster is in-flow at the bottom of the meta column, so it
sits below the From row when collapsed and below the To/Cc rows
when the user expands the recipient details via the chevron.
Cluster is now in-flow with margin-left:auto and flex-wrap:wrap so
when the chip text grows long enough to crowd it, the buttons split
to a second row of icons before they have to cover the chip. The
absolute-overlay behavior kicks back in at very narrow pane widths
(<380px via @container docpane) so From: still fits on one row when
the pane is truly cramped.
Pulled the From row's negative margin from -8 to -4 so the whole
row (From: label AND chip) sits 4px lower together. Action cluster
below now justifies flex-end so the icons sit at the right edge
of the row instead of left-aligned.
Sometimes the user lands in chat mode without realizing — surface the
mode the message went out on as a small uppercase pill right after the
timestamp in the role header.
- roleTimestamp(when, mode) gains an optional mode arg. Agent renders
in accent; Chat renders in muted/neutral. Other values render
nothing (back-compat for older history without the field).
- The three roleTimestamp call sites pass metadata?.mode through.
- chat.js writes mode into the user-message metadata at send time and
into the assistant metadata when the active-stream render lands,
reading toggleState.mode so research/agent overrides upstream still
flow through correctly.
Historical messages from before this change just don't show the pill —
graceful fallback, no migration needed.
