**Implementation** (SVG, not CSS-positioned since `.nw-rx` is an SVG `<text>` child of `.nw-planet-group`): adds a new `<circle class="nw-rx-badge">` to `_drawPlanets` in `sky-wheel.js` BEFORE the existing `.nw-rx <text>` so the text stacks on top of the disc. Both share the same center coords + animate together via a shared `attrTween` on the planet's degree interpolation. Geometry tuned to the user's "commensurately scaled / slightly overlapping" spec: `RX_OFFSET = R.planetR + _r * 0.07` (radial position along the same angle as the planet — keeps badge on the same degree per the user's "along the same degree as it"); `r = _r * 0.035` (70% of the planet circle radius — "commensurately scaled"). Net: badge center sits `_r * 0.07` outside the planet center; badge edge intrudes `~_r * 0.015` past the planet edge — a thin overlap rather than a flush tangent. Glyph font-size bumped from `_r * 0.040 → _r * 0.045` to read better inside the larger disc.
**SCSS** (`_sky.scss`): new `.nw-rx-badge { fill: rgba(var(--secUser), 1); stroke: rgba(var(--priUser), 0.6); stroke-width: 0.5px; }` — light disc w. a thin dark outline to separate it from same-color planet-element rings (gold-greens, etc.) when an Rx planet lands on a matching-color band. `.nw-rx` glyph rule simplified: `fill --priUser`, drops the prior `stroke --priUser` (now unnecessary — the disc gives the glyph its own clean substrate), gains `font-weight: 900` to match the `.shop-badge` text weight contract.
**Why a new SVG element rather than reusing the existing `<text>`'s background**: SVG `<text>` doesn't support `background-color` directly; the canonical pattern is a sibling `<rect>` or `<circle>` underneath. Picked `<circle>` to match the round `.shop-badge` chrome (1.5rem rounded square ≈ disc at the rendered size).
Tests: 198/198 gameboard ITs+UTs green (23s; no test surface — pure SVG render + SCSS change). Visual verify 2026-05-25 PM via Claudezilla on `/dashboard/sky/`: Pluto + Jupiter + Saturn (today's retrograde planets) all carry the cream-disc Rx badge w. dark `R` glyph, slightly overlapping their planet circles along the same angle. No Jasmine spec run — the change is pure DOM-shape augmentation w/o behavioral logic.
