   Alpha-tint tokens for the eyebrow pill + release badges.
   .pen SFAE1 (light) AND zUGk5 (dark): the pill/badge tint BG and
   border stay FIXED lime (#A3E635 @8% / @25%) in BOTH themes — only
   the SOLID foreground (label text, dot) flips to olive in light via
   var(--primary). This is the [DARK-ACCENT-NOT-FLIPPED · tint-bg]
   pattern: tint backgrounds keep the fixed brand hue; foregrounds flip.

   .pen zUGk5 / h3INaR:
   - Section bg: --elevated (design fill end #161B18 ≈ --elevated).
     Grid lines from .hx-grid-bg use background-image and compose
     transparently on top of background-color — no conflict.
   - Eyebrow: pill (lima/olive tint bg + border, radius 100,
     dot ::before). SYS1 already set mono font + uppercase.
     Per-page overrides: inline-flex alignment, pill geometry.
   - Sub: max-width 600px (shared 640px), lh 1.6 (shared 1.55).

   2. RELEASE TIMELINE (module 213, acm-incident-timeline)
   .pen zUGk5 / PBAY5 (List):

   The block normally renders a horizontal 4-col status-step grid
   (connector line + icon node + time + phase + title + text).
   The design shows a VERTICAL 2-col ledger instead. No section head
   (eyebrow/h2 hidden). No connector line. No icon node.

   STRUCTURAL NOTE: The design shows badge chips (NEW/IMPROVED/FIXED)
   per-item. These are NOT emitted by the block template HTML.
   Cannot add via CSS. Reported as SHARED-BLOCK-STRUCTURAL defect
   → acm/incident-timeline/tmpl/style-1.php needs a step_badge field.
