[REFACTOR] Report uniformity: re-vendor CSS/tokens, slot the last inline-sized figures, fix signed-DMS coordinates

[eleanorfrajka]

Summary

Continues the report-subsystem uniformity work (follows #75 and #76). Three things land here: the shared report chrome (stylesheet + design tokens) is re-vendored byte-identical to the sister ctdcast repo and the last two inline-sized figures move onto the slot system; the emit_css accent API is inverted so the vendored files name no package; and a signed-DMS coordinate-parsing bug that was corrupting mooring positions is fixed.

Shared chrome re-vendored + remaining figures slotted

The vendored reports/_css.py and config/report_tokens.py are now byte-identical to ctdcast's copies. This brings the canonical table style (driven by --package-accent), the radius tokens, the .caption/.explainer/.warn prose classes, print_css(), and the quarter slot (W_QUARTER = 2.25).

Downstream follow-ups so the pages match the re-vendored files:

• 39 class="note" renamed to class="caption" across five page templates.

• Per-page table CSS removed from array, grid, instrument, mooring, and stack templates — the table style is canonical in emit_css now. The dense print-oriented recovery table keeps its specialized style.

• The knockdown displacement figure (slot="full") and the instrument speed boxplot (slot="quarter") move from inline style="max-width:…" onto the slot system, so a figure can no longer render at one width while the page displays it at another. The .fig:not([class*="slot-"]) rule keeps a slotted figure from being forced to full width.

Package-neutral emit_css

The per-package accent no longer lives in the vendored files. PACKAGE_ACCENT is removed from report_tokens.py, and emit_css(package: str) (which looked a colour up in that dict) becomes emit_css(package_accent: str) (it takes the colour value directly). Each package now applies its own accent in a local reports/_report_css.py, so the vendored _css.py carries no package-specific edit and re-vendoring it is a byte-identical copy. oceanarray's accent is var(--ocean) (= #1a3a5c), so rendered pages are pixel-identical; the only golden change is the single --package-accent line switching from the hex literal to var(--ocean).

Fix: signed-DMS coordinate parsing (was corrupting mooring positions)

_dms_to_deg mis-parsed a signed "DD MM.mmm" value: the minus on the degrees field did not propagate to the minutes, so "-27 48.000" parsed as -27 + 48/60 = -26.2 instead of -(27 + 48/60) = -27.8 — a ~1.6° error. This flows through parse_latlon into the grid report's latitude-dependent science panels, so it is a data-provenance bug, not just a display glitch. The dune2 fixture's latitude is unsigned, which is why it went unnoticed; its longitude was already wrong. The fix signs the whole magnitude, and _dms_to_deg — previously untested — now has coverage for signed DMS, hemisphere-suffixed, and plain-float inputs.

Separately, the recovery table hardcoded N/ W suffixes and did not parse DMS at all, emitting the malformed "-27 48.000 W". It now routes through parse_latlon_with_source plus a new format_latlon() helper that derives the hemisphere from the sign, so a value can never carry both a minus sign and a hemisphere letter. Recovery-table coordinates now render as e.g. "65.7319° N" / "27.8000° W".

Tests

All pass (773). The golden HTML net (masks figure pixels, compares structure/CSS/text) is re-baselined twice on this branch — once for the table/caption/slot changes, once for the one-line --package-accent switch — both reviewed. New unit tests cover _dms_to_deg, format_latlon, and the quarter slot geometry (with a ±1px tolerance for the 2.25 × 150 = 337.5 half-pixel).

Breaking changes

• emit_css signature and semantics. emit_css(package: str) → emit_css(package_accent: str). It no longer looks a name up in a table; it takes the accent colour value. Migration: call emit_css("<css-colour>") (e.g. emit_css("var(--ocean)")) instead of emit_css("oceanarray"). In-repo callers are updated; this matters to anyone vendoring reports/_css.py.

• report_tokens.PACKAGE_ACCENT removed. The per-package accent dict no longer exists in the vendored tokens. Migration: choose the accent in the package's local reports/_report_css.py and pass it to emit_css.

• Signed-DMS parse result changed (bug fix). Any mooring config expressing a coordinate as signed "DD MM.mmm" (e.g. "-27 48.000") now resolves to a different, correct decimal-degree value. Outputs derived from those coordinates (recovery table, grid latitude-dependent panels) change accordingly. No action needed beyond re-running affected reports.

• Recovery-table coordinate display format changed. From the raw config string with a hardcoded suffix ("65 43.913 N") to hemisphere-from-sign decimal degrees ("65.7319° N").
