Comments join attachments on the card face — a quiet bubble-and-count chip, present-only

A card whose thread holds one comment or more now draws a second trailing chip beside the
paperclip: a secondary-tinted bubble glyph plus its count, shown only when the count is above
zero (design ruling 2026-08-09, card e729e30a). Same styling family as the attachments chip —
caption size, secondary tint, decorative and hidden outright from the accessibility tree — but
this one carries a visible count rather than staying icon-only, per the ruling's own "bubble-style
SF Symbol + count." It sits after the attachments chip at the row's trailing edge, in both the
live title row and the drag replica.

The count is a new `Card.commentCount` field the loader fills with a readdir over `comments/`'s
identity-shaped children that carry their own `index.md` — `BoardLoader.commentCount(in:)`, built
on the same `identityShapedChildren` predicate a trash entry's held-card count already uses. Never
a parse: `.draft` and `.trash/` are excluded for free, the same dot-prefixed hidden-entry skip
`CommentThread.load` documents for both, so the walk stays exactly the O(cards) shape
01-storage-format.md § Enhanced schema already commits to. Because the count rides inside the
`card: Card` parameter `CardFaceView` already takes — not a new parameter of its own — drawing the
chip costs nothing beyond a field read on an already-compared value: no new Observable read joins
the body, and the equatable gate already covers it via `Card`'s synthesized `Equatable`.

The one divergence from the comments pane's parsed count is documented rather than hidden: a
comment folder whose `index.md` exists but fails to parse is a `Stray` the thread read excludes by
opening and rejecting it, a cost this readdir does not pay. The face may then read one comment
high until that folder is fixed or removed — the trade the ruling's "cheap directory-entry count…
not a parse" asks for, over paying full parse cost on every card of every load. Every well-formed
comment, and every card with no malformed one, agrees with the pane exactly.

VoiceOver: `AccessibilityPhrases.cardValue` gains a `comments: Int` parameter, appended after
attachments and before the cut-pending phrase — the same left-to-right order the two chips draw
in, so a sighted read and a VoiceOver read never disagree about which comes first. The trashed
lane row's own call site (an opaque unit with no comments to speak of) passes `comments: 0`.

Docs: DESIGN/03-board-ui.md's card-face section describes both chips and retires the stale "closed
with no growth" sentence, honestly recording the 2026-08-09 growth (the hero banner landed hours
earlier, this chip after it) as exposure of facts the card already carries rather than a body
excerpt. DESIGN/10-accessibility.md's flattened-element sentence gains the comment count.
DESIGN/01-storage-format.md's Enhanced schema paragraph records the chip as shipped. WISHLIST #9
is marked shipped in place — not renumbered, since #10 and #11 are cross-referenced elsewhere.

Tests: CardCommentCountListingTests (BoardLoaderTests.swift) pins the readdir against a synthetic
tree — no comments/ folder, an empty one, non-identity-shaped and index-less strays excluded,
.draft/.trash/ excluded for free, agreement with CommentThread.load's parsed count in the
well-formed case, and the one documented divergence on a malformed index.md.
AccessibilityPhrasesTests covers cardValue's new parameter alone, alongside attachments, and
all three fragments together. ViewEquatableTests pins that a comment landing on a card is a gate
difference. BoardRenderPerformanceTests adds a render-cost guard: one comment added to one card
on a hosted 180-card board re-renders a handful of bodies, not the board.
