/* Role 2 of 2 — the ghost. The design has exactly two button roles: filled accent
   for the action that commits a form (Fetch, Create Worktree), and this outline for
   anything that only opens, reveals or toggles. ONE geometry for every one of them:
   the role had drifted to three different sizes across the panel, all at
   full-strength --text instead of the muted label the design asks for.

   SCOPE — read this before adding a selector. The geometry below covers exactly two
   surfaces: the worktree section (its Prune header button and each row's Open / ✕
   rail) and the diff viewer's toggle and toolbar (View Diff, Working/Staged, ✕ Close).
   Those are the buttons that only open, reveal, switch or dismiss, and every one of
   them is in the list, so none of them can quietly pick its own size again. It is NOT
   a claim about the whole projects panel: at least the following are outline buttons
   by this file's own definition and are deliberately deferred, not overlooked —

     .proj-back           background:none, 1px --border, --text-dim, radius 8,
                          6px 12px, 13px
     .proj-dsession-kill  background:none, 1px --border, --text-dim, radius 7, 30×30
     .proj-claudemd-btn   --surface-2 fill, 1px --border-strong, radius 7, 6px 12px, 12px
     .proj-launch         --surface-2 fill, 1px --border, --text-dim, radius 9, 9px 4px
     .df-push-btn         --surface-2 fill, 1px --border-strong, --text, radius 6,
                          8px 16px, `font: inherit` → 13px from .df-viewer   (W4)
     .df-file-stage       --surface-2 fill, 1px --border-strong, --text, radius 6,
                          3px 10px, 12px      (W4)

   Folding those in touches W4 and the project-detail header, which is a wider change
   than this one. Until someone does it, do not add a further size in the meantime — a
   new outline button either joins the selector list below or matches one of the shapes
   above exactly.

   One exception, and it is in the list not outside it: `.df-tab` can be disabled
   (base-compare mode turns both tabs inert), so it joins :hover as
   `.df-tab:not(:disabled)` — otherwise an inert tab still lit up gold under the

/* The same sunk well the panel uses everywhere for read-only data — fill, hairline,
   radius, padding. That is all this rule is.

   NO HEIGHT CAP, deliberately, and please do not add one back. Three separate capping
   mechanisms were tried on this element and each cost more than the height it saved:

   - `max-height` + `overflow-y: auto` gave a scrollbar nobody can use. mountTimeline
     polls every 5s and render() wipes and re-appends every child (timeline.ts:174-189),
     so scrollTop returns to 0 on every tick — a scroll position cannot survive a
     wipe-and-re-append render loop.
   - `mask-image` softened the cut edge and dissolved the well with it: mask-clip
     defaults to border-box, so the gradient multiplied the --sunk fill, the bottom
     hairline and both bottom corners, and did it on every well including ones that
     clipped nothing.
   - a `::after` gradient overlay does not touch the chrome, but a pseudo-element
     cannot know whether anything is actually clipped, so it fired unconditionally.
     Measured: a 6-event well is 142px tall against a 220px cap and clips nothing,
     yet the 44px overlay covered its last two rows at up to .84 alpha; and in the
     56px empty well it swallowed "No activity yet" outright: --text-dim reads 7.77:1
     on --sunk, and under the overlay that line ran from 5.2:1 at the top of the
     glyphs to 2.6:1 at their baseline — for most of its height BELOW the 3.66:1
     --text-faint value that promoting .tl-empty to --text-dim had just escaped.

   Gating the fade on a row count (`:has(> .tl-row:nth-child(10))`) is refused for a
   different reason, and NOT because it cannot measure: .tl-label is nowrap +
   ellipsis, so every row is exactly one line high and a row count does track the
   well's height. It is refused because it is still a cap. The gate only decides when
   to cut; the cutting is the part every attempt above paid more for than the height
   it saved.

   Un-capped is not unbounded: render() slices to maxEvents, default 50
   (timeline.ts:20), so the well's ceiling is 50 rows and it grows to whatever it
   holds — which is what this element did before any of this CSS existed. What is not
   bounded is the number of wells: buildActivitySection mounts one per running session,
   so the Activity section's height scales with running sessions. That is the price of
   no cap, stated here so the next reader does not have to re-derive it. */

/* ── B1 diff viewer: shell, file cards, diff body, states ─────────────────────
   These classes shipped with names but no rules, so the whole viewer rendered as
   user-agent defaults — white OS buttons and a grey native dropdown on a dark warm
   panel — and the diff body had no +/- signal of any kind. That last part is a
   correctness bug, not a polish one: src/http/diff.ts:143-148 does `line.slice(1)`,
   so the marker character never reaches the DOM and the sign existed only as a
   class name that nothing drew.

   Sits beside the W4 block above so all diff styling lives together. The two button
   roles and the <select>'s skin/caret are joined to their existing blocks further up
   (the "Role 2 of 2" ghost list, and .proj-fanout-mode) rather than restated here,
   so no property is declared twice for the same selector.

   Four surfaces, one hairline each: --sunk code well < --bg viewer body <
   --surface-1 file card < --surface-2 (the W4 Stage button, which needs something
   to sit on top of). Colour is the panel's warm two-tone and nothing else —
   --dirty for insertions (the token already means "uncommitted work", which is what
   a + in a working diff is) and --warn for deletions. No green: :root L23-29
   reserves --ok for the one sync state. No --accent on a state, for the same reason.

   Source order is load-bearing: .df-line and .df-status each sit on the same element
   as their modifiers at identical specificity, so every base is declared before its
   variants and the media query comes last. */

/* One hairline box at --bg on the panel's own --bg — almost invisible on purpose;
   the file cards inside it are what you see. overflow:hidden is load-bearing: the
   toolbar and the W4 commit bar both carry their own fill and are the first and
   last children (diff.ts:407/437), so without it they square off the rounded
   corners.

   font-size is the root of the panel's type scale, and it has to be stated: no
   ancestor sets one (html/body set only a family), so without this the viewer
   inherits the UA's 16px and the three W4 controls that say `font: inherit`
   (.df-commit-msg, .df-commit-btn, .df-push-btn) render as the loudest type in a
   panel whose rail is 12.5px. Every other descendant declares its own size, so
   13px moves those three and nothing else. */

/* Four controls, one of them a <select> sized by the longest branch name, in a phone's

   The rail is view-controls-left, dismiss-right: ✕ Close takes `margin-left: auto`,
   the same `1fr auto` idiom .proj-wt-row spells with a grid. Packing all four left
   instead left a long dead rail after ✕ Close on a wide panel, and on a phone put the
   two tabs alone on line 1 with the rest of that line empty — a toolbar that stops
   partway across is not a group, it is an unfinished row.
   The slack goes to the auto margin and not to .df-base-select (whose 200px cap
   stands) for two reasons: the picker is optional — it only exists when opts.bases is
   non-empty (diff.ts:384-403), so widening it fixes one of the two toolbars the viewer
   can build — and a branch name stretched across half the panel is not more readable
   than one at 200px. The phone half of the void is fixed in the ≤410px block at the
   bottom of the file, where the two tabs split line 1 (`flex: 1 1 0`) rather than
   growing this rule. */

   this viewer. */

/* Both tabs go inert when a base revision is picked — a base diff cannot be staged.
   Matched on :disabled as well, because the click handlers reassign `className`
   wholesale (diff.ts:531/539/575/583) and can drop the modifier while the native
   attribute survives. Must stay after .df-tab-active: same specificity, later wins.

   That source order is doing real work here, not just guarding a hover: updateTabState
   (diff.ts:411-418) only ADDS df-tab-disabled — it never removes df-tab-active — so
   without these three resets the gold "Working" pill survives at half opacity while a
   base diff is on screen, which reads as "selected, and you may click me". Nothing in
   this rule needs a new selector; it just has to undo all three accent properties.

   ONE dimming mechanism, not two. --text-faint AND opacity:.45 stacked to 1.64:1 over
   the toolbar's --surface-1 and took the border with them: on screen both tabs were
   blank rectangles, so you could not see what you would return to. Disabled has to
   read as a label you cannot press, not as an erasure. --text-dim at .55 composites to
   ≈#67635d, 3.03:1 — quiet, still a word. The `color` line cannot simply be deleted to
   get the same effect: .df-tab-active above sets color:var(--accent) at equal
   specificity and would win, restoring the gold pill this rule exists to kill.

   The border is RAISED a tier here, not lowered, and that is not a contradiction:
   opacity multiplies the border along with the label, so this rule has to pre-pay for
   the dimming the way the label does not. Stepping it down to --border (.07) as well
   left .0385 effective — 1.10:1 on --surface-1, against 1.51:1 for every enabled ghost
   button in the same rail — and the tabs read as words floating in nothing.
   --border-strong (.14) × .55 lands at 1.23:1, the same weight as an ordinary --border
   hairline (1.20:1) drawn at full opacity. Still a full reset of all three accent
   properties, which is what the paragraph above requires. */

   Sized to the ghost buttons beside it — 12.5px, 7px vertical — rather than to the
   13px/8px form-field skin: a 1px height mismatch is invisible in a form and obvious
   in a four-control rail. A <select>'s intrinsic width is its longest option and the

   plus two counts, a status chip and a Stage button cannot share one line.
   Scoped to .df-viewer for the same reason the card chrome is: this is the header's
   own box, and .approval-preview (tabs.ts:492-501, which calls renderDiffFile) already
   declares `padding: 8px 10px` of its own — unscoped, the header would nest a second
   one inside it. The line-kind rules further down (.df-line/.df-added/.df-removed/…)
   stay global on purpose: the approval preview should render a diff the same way, and
   the sign gutter and the tints are the part it most needs.

   Smaller unscoped padding, not none. Scoping removed the DOUBLE inset; it should not
   have removed the inset. With only W4's `display:flex` left, the path in the approval
   preview sat flush against the preview's edge and flush against .df-hunk-block's
   border-top while every sibling kept its own (.df-hunk-header 5px 12px, .df-line
   0 12px 0 6px, .df-binary 9px 12px — all still global). 6px 12px 6px 6px is a header
   inset that adds to the preview's 8px 10px instead of doubling it; the scoped rule
   below is (0,3,0) against this (0,2,0), so nothing inside the viewer changes.

   A <button> does not inherit font-family, and the W4 .df-file-stage rule sets a size
   but no family, so Stage was the one element in the panel rendering in the UA's Arial
   beside three mono chips and a --ui-font path. One scoped line fixes it without

   `flex: 1 1 0` and not `1 1 auto`: with an `auto` basis the path's hypothetical
   size is its max-content width, so in a wrapping header the browser breaks the line
   before it ever shrinks the item — the ellipsis never fired, and a long path evicted

   Assumed: every face in --mono-font has a weight-invariant advance. `ch` resolves
   against the pseudo-element's OWN font, and .df-added/.df-removed make it bold while
   context lines stay regular, so a mono face whose bold digit-zero is wider would shift
   changed lines horizontally against unchanged ones and break the column alignment this
   gutter exists to keep. The named faces in the stack (ui-monospace, SFMono-Regular,
   Menlo, Consolas) hold the advance across weights; the last entry, the generic
   `monospace`, resolves to whatever the platform picks and is not required to. Keep
   the units in ch regardless — that is what keeps the gutter on the mono grid; if a

   The row wash follows the house "this row is in the marked set" idiom from
   .proj-commit-unpushed (a low-alpha tint plus a bar), flat rather than that rule's
   90deg fade because a diff line is arbitrarily long and a fade to transparent at
   55% would drop the tint off the end of exactly the lines you most need marked.
   The bar is box-shadow so ::before stays free for the sign.

   The two washes are deliberately NOT the same hue at two alphas: --dirty and --warn
   are both warm oranges, and at wash strength over --sunk they compute within four
   points of each other — indistinguishable, so the tint would be doing no work.
   Insertions take a neutral white lift instead (the same rgba(255,255,255,…) idiom
   as --border), deletions take the warm --warn wash. Neutral-lift vs warm-wash reads
   at a glance, and it spends no new hue — green is not available here, per :root
   L23-29. Full-strength colour stays on the bar and the +/- glyph.

   The insertion lift is .085 and not .045: at .045 it composited to #171614, ΔL* 4.3
   against --sunk (1.09:1) — invisible — while the deletion wash lands at ΔL* 13.2 plus
   a hue shift. Deletions read instantly and insertions read as context, which is
   backwards for the half you are about to commit. At .085 the lift is ΔL* 9.1, still
   the quieter of the two, which is the intended order.
   The deletion wash is 24% and not 16%. At 16% the two composited to within 1.0 L* of
   each other, so added-vs-removed rested almost entirely on a low-chroma hue shift —
   and the two full-strength cues both live in the first 6px of the line, so scrolling a
   long line right inside .df-lines carries the inset bar and the ::before glyph out of
   the scrollport and leaves the wash alone to do the job. 24% separates in the browser
   and is still warm rather than loud. The insertion lift stays at .085: neutral vs warm
   is the axis, and lifting both would just re-close the gap.
   The bar is 3px and the glyphs are bold for the same reason from the other end: on a
   greyscale or dimmed phone screen the wash is all but gone, so the sign and the rule
   down the side have to carry the distinction by shape alone. */

   It must NOT extend to the whole ≤720px band, which is where it used to live. Once
   the picker joins the tabs on line 1, a zero basis makes them absorb every pixel the
   picker's cap frees — and those pixels are the auto margin that pins ✕ Close to the
   right edge, so the dismiss control drifted back into the group.

   410px and not 720px because the seam is the width at which the picker's basis can
   first share the tab line, and that width is not one number: it moves with the UI
   font, and the panel is narrower by a classic scrollbar on desktop than by an overlay
   one on a phone. 410 covers the wider of the two models. Erring that way leaves the
   rule live but idle across the few pixels where the phone model has already put the
   picker on the tab line — which costs nothing — while erring the other way would
   leave the void unfixed on the devices that have it. Not pinned tighter than the
   nearest ten, for the same reason.

   `flex: 1 1 0` and not `1 1 auto`: a zero basis still has min-width:auto, so each
   tab's hypothetical size stays at its min-content word width and the line-breaking
