  "_comment": "MINERAL HUD — the ship's hold readout in the UPPER-RIGHT corner (the old tether stack's spot): the 'MINERALS  n / N' line over a fill bar. The bar IS the hold — fill = minerals aboard (ship.minerals) / capacity (ship.stats.mineralStorage), filling left→right; set() animates the number counting up and the bar sliding with it, and a brief cyan flash ripples over the bar when minerals land; at capacity the fill turns theme 'amber'. pad/lineGap anchor the block to the corner (right margin, top margin); bar = the track (width/height px, border = the 1px frame, inset = how far the fill sits inside it); label = the number's font; countUp = the shared number+bar animation; flash = the landing ripple (alpha at t=0). Palette: neon = live (theme 'neon'), amber = full (theme 'amber'), track* = the command deck's slot colors (data/actionbar.json).",
