/* Month arrival cue — hairline opener for secondary month groups.

   The blog index is an Explore surface, and .month-nav exists
   specifically to jump readers straight to #m-july, #m-june, etc.
   But until now .post-month was the only section-opener on the
   site that didn't carry a hairline arrival mark: every other
   labelled opener (.has-divider on the home page, .post-year
   above, .projects-cat-label, .keep-reading-title) uses the same
   "mono label + hairline" rhythm to signal "a new surface begins
   here." A reader who clicked "July" in the month-nav landed on
   plain uppercase text floating mid-list, with no visual stop
   confirming the jump target.

   This closes that gap the same way the rest of the site already
   does: a whisper-thin --border2 rule above the label, plus a
   small padding step so the label doesn't sit hard against the
   rule. The :not(.post-year + .post-month) guard keeps the first
   month under a year (e.g. August) untouched — it already
   inherits the year's own establishing hairline directly above,
   so adding a second rule there would just stack two lines
   fractions of a millimeter apart. Subsequent months (July,
   June, May) get the cue instead, which is exactly where it's
   needed: each is a fresh jump destination in the middle of a
   long scroll, with no other visual marker around it.

   Reuses the existing --border2 token (.post-year's own rule,
   .has-divider's opener) — no new box, icon, color, or token.
   The rule is on the same element that carries data-divider,
   so it composes with the topic-filter dimming already in
   [data-divider].is-dimmed: when a month has no matching rows
   in an active filter, the whole element — label and rule
   together — fades to 0.3 opacity rather than leaving a bright
   hairline hovering over an empty stretch. */

/* Legacy .back selector (for old-style posts)
   ~67 articles ship the back link as the first child of <article>,
   directly above the <div class="meta"> date row. The original rule
   gave it only margin-bottom: 32px against that byline, leaving it
   visually trapped between the sticky nav chrome and the article's
   dateline. The 38 modern articles solve this with a separate
   .back-link wrapper (720px container, its own 32px breathing room).
   This refactor gives the bare .back the same air gap purely via
   CSS, scoped to its real structural position (the immediate
   previous sibling of .meta), so all 67 old-style articles get the
   unified treatment at once with no HTML changes.

   Design posture (Decide/Learn reading surface): the back link is a
   wayfinder, not a feature. Linear's restraint holds — no box, no
   icon, no accent fill. The change is purely spacing + ink: the
   link shifts one ink tier brighter than it was (fg3 vs fg4) so it
   reads as a findable affordance, gains a hairline at its own
   bottom edge, and pulls down to clear the byline beneath. The
   "larr" glyph already spaces via gap:4px; no new decoration. The
   hairline reuses the existing --border token (.post-row separators,
   .article-tags end-rules) — no new token, no new box. */

   set below) for the h1 separation; the 28px gap above the meta
   replaces the 32px that used to sit between back and byline, while
   the hairline at the link's bottom edge establishes the visual
   stop instead of empty margin. margin-top stays zero so the link
   keeps the original 64px distance from the nav rather than drifting
   away from it. Only fires when a .back link is the direct article
   child and immediately followed by a .meta row — the exact
   structural shape of all 66 old-style articles using <article> —
   so the 38 modern posts using .back-link separately never collide.

/* Blockquote — Linear full-enclosure treatment, no left-border accent rail.
   The prior border-left: 3px solid accent was an accent-rail slop tell
   (decoration pretending to be organization). Linear encloses callouts
   with a uniform hairline border and lets indentation + muted ink carry
   the "this is a quote" grammar. Indentation is preserved via the left
   padding so the row reads as set-off prose, not as a colored strip.

   Editorial quotation glyph (::before) — the typographic mark that signals
   "this is a quote" without using a colored strip, icon, or box. This is
   how editorial publications (Stripe's blog, the NYT, literary magazines)
   anchor a pulled quotation: a large dimmed " character in the article's
   left margin gutter, where marginalia lives. Linear's own restraint holds
   here — the glyph is type, not decoration: a single 4xl glyph in the
   quaternary ink tier (var(--fg4) ≈ #62666d), positioned in the left gutter
   at 8px and bottom-anchored to the top of the quote so its baseline sits
   against the opening line. No new color, no new token, no new box — just
   type set-as-hierarchy at a scale the body cannot carry.

   Spatial reasoning: the article body is centered at max-width 720px, so
   any viewport wider than 720px + 2×24px padding leaves dead margin space
   on both sides. The glyph lives there at left: -28px, occupying no
   content width. On narrow viewports (≤ 720px + padding) the article
   spans most of the width and the left gutter closes; a max-width: 880px
   media query hides the glyph so it never collides with the body text or
   gets clipped off-screen. Below that, the hairline + muted ink still do
   the full job of marking the quote — the glyph is a marginalia gain for
   wide viewports, not a load-bearing signal. */

      one large mono number per card (fastsdcpu, apertus, turbovla).
   2. Row-pair table: .bench-label / .bench-row / .bench-tool /
      .bench-time — key/value pairs stacked inside a card with
      hairline separators (oak-version-control, gpt-5-6-sol,
      reame-cpu-first, and ~30 other articles).

   The grid uses auto-fit so the same component renders two columns
   inside the 720px article body (672px content / 280px min = 2) and
   collapses to one on narrow viewports — replacing the old fixed
   1fr 1fr that needed a media query the original desktop-first

/* --- Row-pair table variant ---
   These class names previously had to be inline-<style>-defined in
   every article that used them (33 files), and the definitions
   drifted: some articles stapled rows without hairlines and printed
   the value in --fg (white) instead of the accent, others used
   baseline alignment + accent-bright, and font sizes moved between
   rem and px on each rewrite. Pulling them into the shared
   stylesheet normalizes every benchmark table on the site to one
   on-system treatment: baseline-aligned label/value, hairline row
   separators (the same --border token the .post-row list uses),
   and Mono-on-accent for the measured value — Linear's numeric-
   emphasis register for a Compare surface inset inside a reading
   surface. */

/* .bench-label: the section title inside a row-pair card.
   Mono, fg3, xs caps tracking — the same .spec-label /
   .bench-card .label recipe so the two variants read as one
   family. Carries the row group's name (e.g. "Run summary",
   "13-year-old Xeon, AVX1 only").

   Hierarchy refinement: the label was previously only separated
   from its rows by 12px of margin, so on a 4-5 row card it read
   as the first row rather than as the row group's header. Linear's
   Mono Label spec anchors a data block under a label with a hairline
   separator — the exact pattern .post-year and .projects-cat-label
   already use on this site. A bottom hairline (the existing --border
   token, no new color) followed by a tight 10px gap closes the
   label-to-first-row relationship so the rows read as the content
   of the label, not as another peer. The first row's own top
   hairline is suppressed so the label hairline is the single opener.

/* =========================================================
   ARTICLE-END SIGNATURE FOOTER
   A quiet editorial close for blog posts — the essay's final
   rule, a mono signoff, and three small nav links. Replaces
   the chaos of ~10 unstyled per-post footer variants
   (bare <p>, .left/.right, .footer-quote/.footer-links/
   .footer-signoff, .signoff, .quote…) with one consistent,
   scoped component.

   Design posture: this is a Decide/Learn reading surface,
   so the close is hairline + type, never a card or CTA
   banner. The hairline matches the .tags end-rule already
   used at the bottom of article bodies; the mono signoff
   reuses the exact .read-time / .section-title recipe; the
   links reuse the muted footer .right a treatment. Nothing
   new is invented — existing tokens are reused deliberately.

   Scope: `article footer` and `article > footer` override the
   site-wide `footer` rules (which target the 960px page
   footer on index/about/projects) so article footers stop
   inheriting a 960px flex strip and instead stay inside the
   720px reading column. The `.post-footer` class is the
   canonical hook for footers placed outside <article> (older
   posts); it carries the same scoped rules.
