fix(blocks): restore legacy values with token-gap markers

Tasks 10 and 11 documented that the first attempt pointed raw values at
the nearest --step-* / palette token. That is a silent redesign: --step-1
is 15px where source uses 14px, var(--muted) is #697b89 where source uses
#9eabb4, and so on. The brief says the site must look exactly as it did.

check-tokens.mjs (synced from main) now waives findings whose own line or
the line above carries 'token-gap: <reason>; owner design-system-keeper'.
Marked values are printed every run as a visible debt queue for
design-system-keeper; the marker needs a real reason or it does not count.

Restored to the exact legacy values:

  FleetDiagram   captain-eyebrow 10px, captain h2 clamp(24,3vw,38),
                 arrow 30px, workers parent #41596b seam,
                 worker-card span color #9eabb4 + font 10px,
                 worker-card strong 16px
  HandoffTable   thead 10px, tbody th 14px, td 13px
  PhasePanel     phase-tab 10px, phase-meta 10px, panel h3 clamp(24,3vw,38)
  RouteTable     head 10px, strong 14px, small 12px
  SkillPackage   label 10px + #ffffff40 borders, row 12px code (no weight)
  WorktreeMap    border 1px solid #41596b, span 9px, strong 14px,
                 small color #9eabb4 (root and branch)

Values that already matched a token (captain/worker code at --step-0=11px,
the panel code, all the layout/spacing values, colours that did match)
are untouched.

gate passes; 19 marked token-gaps await design-system-keeper; no raw
hex or px font-size is unmarked.
